A parallel study between the alternative of the conventional truck haulage with the primary crusher loed outside of the pit and the inpit crushing and conveying alternative can be a long, expensive process. Mining companies with portfolios that contain many open pit projects usually face issues in evaluating the benefits of an IPCC implementation due to the massive workload and time ...

Sulphide ore is treated via crushing, milling and flotation to produce copper in concentrate. Mixed ore is treated through a similar circuit with the option to treat the flotation concentrate via the high pressure leach circuit. Oxide ore is treated via crushing, milling, flotation, leaching and the SX/EW process to produce a sulphidic and gold bearing flotation concentrate as well as electro ...

For example, most copper deposits have a grade of less than 1% Cu, which is very low. The ore value without processing could justify its mining, but usually, it doesn't, especially for underground mining. The ore should be upgraded to 20%, at least, to be sold and cover the mining costs. 2. increasing the ore value

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copperbearing minerals from it. To be applicable to this process, the ores must contain copper minerals in sulfide form ...
