TLT Turbo Africa fans boost ventilation and savings
TLT-Turbo Africa's new range of auxiliary and booster fans have not only improved ventilation in deep mines but yielded capital payback in under three months.
The company was approached by an ultra-deep mining operation located in Gauteng, requiring a recommendation for a suitable fan.
“Following numerous engagements, our Engineering and Research and Development teams set out to develop a customised solution, utilising our high efficiency A&B fan range,” Vusi Madlopha, TLT-Turbo Africa Head of Sales & Business Development relates.
At the time, the operation was using multiple installations of auxiliary fans to deliver the required volume and pressure (consuming ±630kwe). The mine was also operating three main surface fans, each consuming ±2MW of power.
Based on an assessment of the mine’s needs, the final recommendation made by TLT-Turbo Africa was for two MC1600AP-160KW dual stage fans from the newly launched A&B fan range (specifically 1600mm diameter, dual-stage fans, each fan driven by two 160kW high-efficiency motors).
The R&D team custom-designed the required fans to be modular, allowing their transport through shafts and access tunnels and once on site, they were easily assembled.
Three months after the installation, conditions underground at the shaft have improved noticeably, particularly in the previously warmer upper levels.
The installation and commissioning of the TLT-Turbo Africa fans has allowed the mine to permanently remove 14 other auxiliary fans (with a total rated power of 630kW).
The capital pay-back period on this project has been less than three months and with the lifespan of this project exceeding 10 years, the implied electrical cost savings of this solution are massive, the company states.
Newmont acquires Canada’s GT Gold in $325mn deal
Newmont, the world’s biggest gold miner, has acquired Canada’s GT Gold in a deal worth $325mn. The gold giant now controls the Tatogga gold-copper project in the Traditional Territory of the Tahltan Nation.
“With the acquisition of GT Gold and the Tatogga project in the highly sought-after Golden Triangle district of British Columbia, Canada, Newmont continues to strengthen our world-class portfolio,” commented Newmont President and CEO Tom Palmer.
“We look forward to continuing to build a respectful and meaningful relationship with the Tahltan Nation, including the community of Iskut. The relationships we have with Indigenous communities, First Nations and host communities are critical to the way we operate. We will partner with the Tahltan Nation at all levels, and with the Government of British Columbia to ensure a shared path forward as the Company understands and acknowledges that Tahltan consent is necessary for advancing the Tatogga project.”
Newmont’s acquisition includes the Tatogga project, comprised primarily of the Saddle North deposit, which has the potential to contribute future significant gold and copper annual production. There are also further exploration opportunities beyond the known deposits at Saddle North within the land package. The Tatogga project adds to Newmont’s existing interest in the prospective Golden Triangle through the company’s 50% ownership in the Galore Creek project.
Newmont is the world’s leading gold company and a producer of copper, silver, zinc and lead. A world-class portfolio of assets, prospects and talent is anchored in favourable mining jurisdictions in North America, South America, Australia and Africa. The American miner is celebrating its 100th anniversary this month.
With gold prices on the rise, the last six months has seen gold industry M&A activity accelerating. A recent Mckinsey report, advises that the industry need to be mindful of mistakes made during the previous gold price boom, when growth was chased unidirectionally by several companies.
