Stages 1 and 2: Bashing and Mashing. Traditionally, the process selection choice was between a conventional, welltried, threestage crushing circuit followed by ballmilling, or singlestage crushing followed by a SemiAutogenous (SAG) mill and ball mill. The latter is preferred for wet sticky ores to minimize transfer point chute blockages ...

This research is focused on the Phase I SABC milling circuit of the Wushan porphyry copper mine. Improvements to the existing circuit were targeted without any significant alterations to existing equipment or the SABC circuit. JKSimMet simulations were used to test various operating and design conditions to improve the comminution process. Modifications to the SABC comminution circuit included ...

2. Grinding process. The copper ore processed into granules is screened by a vibrating sieve and sent to a ball mill for grinding and crushing. Here also need to use an auxiliary equipment classifier. It can classify and screen copper ore and release copper ore powder that meets the requirements. 3.

Fig. 14 shows the screening equipment for a copper ore processing plant operated by Vale in the Solobo mine, which processes 24 Mta of copper ore annually. A crucial feature of this plant is that the secondary crushing is performed by highpressure roller presses (HPGRs), which already produce a high proportion of fines.

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel ...

Milling the mined ore through crushing and grinding. Ball or rod mills crush and grind the mined ore to fine particles, releasing molybdenite from the gangue (worthless rock). The grinding mills shown here reduce rocks from the size of soccer balls to the size of gravel. Further ball milling reduces the material to the consistency of face powder.
