Gold processing 101
Some other key drivers in flowsheet selection at the hashing stage are: Supergene weathering. This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to 'free-milling' gold, behaving in a similar fashion to gold …
Minerals & Mining Industry: Bulk Handling and Conveyor …
Our systems easily master steep inclines, rivers, and roads. Coal, ores, and minerals can be transported on the conveyor belt from the mine to the blending bed in just one hour, even on winding routes up to 25 km long. Energy-recovering systems along the way can utilise downhill sections of your route and feed electricity back into the public grid.
