in the PGE sector. Historically, primary producers of PGE metals have controlled the flow of information relating to the mining and processing of these ores into the public domain. Very little published information relating to individual operations and processes is available in comparison to the available literature relating to other metals.
Jun 18, 2021 The equipment processing capacity is large, the operation is simple, and the application is wide. It is suitable for processing coarse-grained minerals with uneven inlays, and can obtain the final product in a single separation. 2 Spiral Chute. It belongs to the slant flow separation the processing particle size range is generally 2-0.03mm.
Coarse liberation of minerals at the start of the process reduces energy input and this has flow-on effects for energy savings during downstream processing. The type of comminution device employed by a mining operation is extremely important for minimising energy costs and maximising profits.
The mining fleet comprises PC2000 and PC1250 Komatsu excavators, HD785 Komatsu trucks, ECM 720 Production drills, WA900 Komatsu front end loaders and Komatsu dozers and graders. With a processing capacity of 4.6Mtpa, the processing plant is estimated to produce 250,000oz of gold and four million ounces of silver.

Mining and processing activity at Pe asquito mine. Run-of-mine RoM oxide ore is delivered onto a heap leach pile using haul trucks. It is added with lime before being placed on the pad, and leached with cyanide solution. The leached solution is then clarified, filtered and de-aerated, treated with zinc dust to precipitate the precious metals.
