Jul 18, 2017Iron ore mining was previously undertaken by American and European companies in the areas of Bomi Hills, Bong Mines, Mano River, and Nimba. Those concessions resulted in widespread clearance of tropical rainforest for mines (open-cast pits), processing plants, housing and roads, railways, and unmanaged deposit sites.

The ROL technology could be a game-changer for the gold industry displacing current refractory processing methods, Flanagan says. When we have proven this technology successful, miners will be looking at a completely different life of mine plan; by lowering the cut-off grade, more ore will be converted into reserves, extending mine life.

A review has been completed of current and proposed processing technologies for nickel laterite ores. Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore needs to be treated in the process.
