Alphamin Resources has the backing of the North Kivu Government in its flagship Bisie Tin Project, the company has revealed.

 A committee has been established by the North Kivu Government to support Alphamin subsidiary, Alphamin Bisie Mining (ABM) S.A. to develop the Bisie tin project. ABM will develop the Bisie Tin Project with plans to begin full production in 2019.

North Kivu Governor Julien Paluku Kahongya signed the legal order in Goma on 20 December, 2016 creating the Committee to Accompany ABM in Implementing its Mine at Bisie (CAIMB in French) in order to both support ABM.

The CAIMB is composed of high-level technical and specialised services who will help guide ABM for the three years of construction and initial operations. A branch of the CAIMB will be created in Walikale Territory to engage with local authorities in the same way.

Confirming the Province's strong commitment to promoting private investment and public-private partnership in North Kivu, Governor Julien Paluku stated: “The provincial government is committed to providing a favourable environment for private investment in a win-win partnership. We affirmed this in two economic forums of the province held in 2010 and 2015. North Kivu has indeed an enormous economic potential to exploit for the benefit of its population. We must support Alphamin, so that other investors in the mining, agriculture, energy and tourism sectors are reassured to follow the example and invest responsibly."

The North Kivu provincial minister in charge of mines, Professor Anselme Kitakya, who is responsible for the smooth operation of the CAIMB, adds: "Alphamin is already demonstrating the importance of partnership with the government of North Kivu by co-financing the rehabilitation of the Sake-Masisi-Walikale road for approximately 230 km and through the contribution to social development within the framework of the Lowa Alliance, a non-profit foundation initiated by the populations that will be supported by the mining project that develops ABM in the territory of Walikale. Socio-economic infrastructures will be erected in the area surrounding the Bisie mining site. We are committed to providing support and advice to investors such as ABM."

 Alphamin CEO Boris Kamstra commented, “North Kivu has many assets and remarkably industrious people, from which past events have diverted investors’ attention. This is a very encouraging sign and helps us in our role as ambassadors for North Kivu to global investors to convey the support of government, nationally, provincially and locally which will assist Alphamin with the development of our Bisie Tin Project.” 

Read our exclusive interview with Boris Kamstra on all things Alphamin, North Kivu and the lasting legacy of the Bisie Tin Project.

 Richard Robinson, Managing Director of ABM, echoed these sentiments: “As the Bisie Tin Project moves forward in road and preliminary construction activities, including the ventilation tunnel, we are seeing increasing support from local and national stakeholders through actions such as that of the North Kivu Governor.  This reinforces the progress made by Alphamin in 2016 with the signing of a collaborative Memorandum of Understanding with the Walikale Community in April and June, 2016, followed by concrete social development projects such as the construction of the new Luuka Primary School and the formal founding and registration of the Lowa Alliance, as well as partnerships with North Kivu and the national road agency in rehabilitating the Masisi Walikale road.”

 It is anticipated that ABM will employ approximately 700 people during construction and will create approximately 450 permanent local jobs during operations. As a result, significant economic benefits are expected in an area of the DRC that has seen little foreign investment while overcoming security and governance challenges for decades. The mine is estimated to produce 10,000 tonnes of tin in concentrate on average per year over the 12-year mine lifespan, which represents about 3% of the world’s current production and will double the DRC’s current tin exports.  Alphamin and North-Kivu actors understand the project will serve as an example for foreign investment and will also serve as an infrastructure platform for other businesses to start, including service providers to the mine.  Indirect job creation will be far higher than the mine's direct numbers and can be reasonably expected to achieve the 1:14 ratio of indirect jobs commonly reported in Africa for similar projects, resulting in potentially an additional 6,300 jobs.

McKinsey: adopting a smart approach to big data

Industrial companies are using AI to improve plant operations. To be successful, they will need to leverage big data with the help of domain experts

Industrial companies are embracing artificial intelligence (AI) as part of the fourth digital revolution. AI leverages big data; it promises new insights that derive from applying machine learning to datasets with more variables, longer timescales, and higher granularity than ever.

Big Data

According to a new McKinsey report, using months or even years’ worth of information, analytics models can tease out efficient operating regimes based on controllable variables, such as pump speed, or disturbance variables, such as weather. These insights can be embedded into existing control systems, bundled into a separate advisory tool, or used for performance management.

Artificial Intelligence

McKinsey recommends that to succeed with AI, companies should leverage historical data via automation. They will need to adapt their big data into a form amenable to AI. This ‘smart data’ can improves predictive accuracy and support root-cause analysis. Additionally, bolstering and upskilling expert staff to manage the process can result in an EBITDA increase of 5 to 15%.

Smart Data

A common failure mode for companies looking to leverage AI is poor integration of operational expertise into the data-science process. McKinsey advocates applying machine learning only after process data have been analysed, enriched, and transformed with expert-driven data engineering using the following steps:

Define the process

Outline the steps of the process with experts and plant engineers, sketching out physical changes (such as grinding and heating) and chemical changes (such as oxidation and polymerization). Identify critical sensors and instruments, along with their maintenance dates, limits, units of measure, and whether they can be controlled.

Enrich the data

Raw process data nearly always contain deficiencies. Thus, creating a high-quality dataset should be the focus, rather than striving for the maximum number of observables for training. Teams should be aggressive in removing nonsteady-state information, such as the ramping up and down of equipment, along with data from unrelated plant configurations or operating regimes. Generic methods to treat missing or anomalous data should be avoided, such as imputing using averages, “clipping” to a maximum, or fitting to an assumed normal distribution. Instead, teams should start with the critical sensors identified by process experts and carefully address data gaps using virtual sensors and physically correct imputations.

Reduce the dimensionality

AI algorithms build a model by matching outputs, known as observables, to a set of inputs, known as features, which consist of raw sensor data or derivations thereof. Generally, the number of observables must greatly exceed the number of features to yield a generalized model. A common data-science approach is to engineer input combinations to produce new features. When combined with the sheer number of sensors available in modern plants, this necessitates a massive number of observations. Instead, teams should pare the features list to include only those inputs that describe the physical process, then apply deterministic equations to create features that intelligently combine sensor information (such as combining mass and flow to yield density). Often, this is an excellent way to reduce the dimensionality of and introduce relationships in the data, which minimize the number of observables required to adequately train a model.

Apply machine learning

Industrial processes can be characterized by deterministic and stochastic components. In practice, first principle–based features should provide the deterministic portion, with machine-learning models capturing the statistical portion from ancillary sensors and data. Teams should evaluate features by inspecting their importance and therefore their explanatory power. Ideally, expert-engineered features that capture, for example, the physics of the process should rank among the most important. Overall, the focus should be on creating models that drive plant improvement, as opposed to tuning a model to achieve the highest predictive accuracy. Teams should bear in mind that process data naturally exhibit high correlations. In some cases, model performance can appear excellent, but it is more important to isolate the causal components and controllable variables than to solely rely on correlations. Finally, errors in the underlying sensor data should be evaluated with respect to the objective function. It is not uncommon for data scientists to strive for higher model accuracy only to find that it is limited by sensor accuracy.

Implement and validate the models

Impact can be achieved only if models (or their findings) are implemented. Taking action is critical. Teams should continuously review model results with experts by examining important features to ensure they match the physical process, reviewing partial dependence plots (PDPs) to understand causality, and confirming what can actually be controlled. Additional meetings should be set up with operations colleagues to gauge what can be implemented and to agree on baseline performance. It is not uncommon for teams to convey model results in real time to operators in a control room or to engage in on-off testing before investing in production-grade, automated solutions.

Conclusion

Industrial companies are looking to AI to boost their plant operations—to reduce downtime, proactively schedule maintenance, improve product quality, and so on. However, achieving operational impact from AI is not easy. To be successful, these companies will need to engineer their big data to include knowledge of the operations (such as mass-balance or thermodynamic relationships). They will also need to form cross-functional data-science teams that include employees who are capable of bridging the gap between machine-learning approaches and process knowledge. Once these elements are combined with an agile way of working that advocates iterative improvement and a bias to implement findings, a true transformation can be achieved.
