The recent announcement of new DSO resource estimate in its Tonkolili project has African Minerlas looking forward to expanding saprolite production

African Minerals has established itself as a successful minerals exploration, development and mining company.  Most recently, the company’s primary focus has been on its Tonkolili Iron Ore Project in Sierra Leone and today they have announced an increase in its Direct Shipping Ore (DSO) resource at this location. The updated mineral resource estimate reflects that 43.9 million tons of DSO material has been mined since the beginning of the project through March 2014, but the delineation of the 59.5 million tons per year of DSO has provided the resources to extend the life of the operations in Sierra Leone.

Excited by this new discovery, chief executive officer, Bernie Pryor, states that, “the increase in the Tonkolili DSO resource is a significant event. The increased life of the DSO resource, now with over ninety percent classified in the Measured and Indicated resource categories, will allow the company to produce to 2020, and to take a longer term vie regarding the current operations.”

Mining Weekly follows-up on this company issue, saying, “Production of DSO will be concurrent with our near-term plans to expand production to 25Mtpa and to move into a higher value of saprolite hematite concentrate product from 2016. This new resource estimate also reflects that the last estimate was derived at several other locations.  Therefore a revised cut-off grade of 53.5 percent iron, compared to 56.5 percent which was previously estimated, which a portion of this material has been classified as ‘High Grade Saprolite Ore’.” 

Due to this DSO Mineral Resource estimate, an updated saprolite resource (including optimized metallurgical parameters) is expected to be available by summer 2014. African Minerals looks forward to increasing its production capacity from 20 million tonnes per year to 25 million tonnes per year, and anticipates being able to drastically increase the output of saprolite per year.   The company is pleased to announce its expectation of establishing its first ever saprolite concentrator by early 2016, which will allow them to have the ability to further assess the metallurgical properties of the saprolite component of its Mineral Resource, and therefore produce it at a higher value. This operation will be running simultaneously with the DSO operations.

In addition, African Minerals has been developing port and rail infrastructure, forging strong partnerships with Shangong Iron and Steel Group and China Railways Materials Commercial Corporation to support the Tonkolili Project.  

"We are, of course, excited to embark on this next stage of our expansion, for which we expect to provide more information in due course. The first step of this expansion will be the publication of an updated saprolite resource later this quarter, incorporating the adjustments to the DSO resource as announced today,” reports Pryor.

Ericsson Private 5G is a next-gen private cellular 4G & 5G network tailored to drive Industry 4.0 and the digital transformation of industries like mining

Ericsson has launched Ericsson Private 5G. It offers secure and simple 4G LTE and 5G Standalone (SA) connectivity primarily targeting manufacturing, mining and process industries, offshore and power utilities, as well as ports and airports.

 

Ericsson

Ericsson Private 5G optimizes and simplifies business operations with cloud-based network management, keeps sensitive data on-premise, has zero downtime upgrades and guarantees high performance through Service-Level Agreements (SLAs).

It is easily installed within hours at any facility and can be scaled to support larger coverage areas, more devices and higher capacity when needed. The product is designed to be flexible and will support a range of deployment sizes, depending on requirements, to suit varied needs. Businesses can manage their networks and integrate with IT/OT systems via an open API.

5G

Ericsson Private 5G builds upon Ericsson’s 4G/5G radio and dual mode core technology, enabling a wide variety of use cases for both indoor and outdoor environments while integrating well with business operations, devices and applications. As a result, companies can improve productivity, give their customers more value and provide better working environments for employees.

Innovative use cases include tracking assets and real-time automation to improve productivity in warehouses, and a digital twin that can help to optimize manufacturing operations. Efficient quality inspections can also be performed via augmented reality or smart surveillance drones to increase worker safety, particularly in potentially hazardous environments such as ports and mines.

Boliden

Ericsson already has a significant track record of operational 4G and 5G private network deployments with customers worldwide. Ericsson Private 5G builds on the success of that solution portfolio and deployment insights, as well as insights from projects such as 5G-Industry Campus Europe.

Peter Burman, Program Manager Mine Automation, at Swedish mining company Boliden, commented: “Automation, and safety through automation in our mining operations is an absolute must for us. Ericsson Private 5G is exactly what Boliden needs to bring high quality, fast and secure connectivity into potentially hazardous environments allowing us to mobilize efficiency and safety improving use cases.

Niels König, Coordinator 5G-Industry Campus Europe, Fraunhofer Institute for Production Technology IPT added: “Private 5G networks are highly attractive for producing companies because of the uncompromised performance that 5G can bring, allowing them to tackle the challenges of production. Efficiently deploying and using network solutions in enterprises requires simplicity in installation, flexibility in connecting to existing production IT and lean operations while at the same time being able to scale the network to meet future challenges. Ericsson Private 5G delivers exactly these capabilities.”

Enterprise Networks

Leo Gergs, Senior Analyst, ABI Research, noted: “With this new offering, Ericsson will be able to address key trends in the enterprise cellular market.  The value proposition will appeal to operators and service providers as the solution hides technology complexity and therefore reduces the barrier of entry to deployment for many different flavors of enterprise networks.”

Thomas Noren, Head of Dedicated Networks, Business Area Technologies and New Businesses, Ericsson, revealed: “With Ericsson Private 5G, we take the best of Ericsson’s current portfolio and top it up with the best of our new technology. We do this to give businesses what they need to improve productivity, enable new offerings and give employees a better working environment. With Ericsson Private 5G, we also give operators a better way to serve business customers and leverage their assets - in short, to grow beyond mobile broadband.”

Ericsson recently joined a three-year initiative to develop autonomous, carbon-neutral mining processes supported by 5G connectivity. Funded by the EU’s Horizon 2020 research and innovation program, the $16mn Next-Generation Carbon-Neutral Pilots for Smart Intelligent Mining Systems (NEXGEN SIMS) project is being coordinated by Swedish mining and infrastructure equipment manufacturer, Epiroc, in cooperation with a range of industry-diverse partners, including: Ericsson, K+S, Boliden, Agnico Eagle Finland, KGHM Polska and Luleå University of Technology.
