Processing of Complex Materials in the Copper
Current technology to extract low-grade copper reserves indicates that higher-grade copper deposits are not necessarily mined first. Many low ore grade deposits remain operating as is the case of Morenci, High-power laser rock cutting and drilling in mining operations: initial feasibility tests.

(1977) ImageHeap leaching technology is finding increasingly widespread application to recover values from low-grade ores, especially in the gold and copper industry. The particular attractiveness of the process is the relatively low-cost recovery of the target metal at site without the need for energy intensive comminution, providing the process can beHeap leaching as a key technology for recovery of values from low-grade

Iron ore beneficiation: an overview ScienceDirect
Processing of low-grade ore. Flow-sheets for low-grade ore processing of different iron ore mines vary significantly; however, the underlying principle of operation is very similar. Methodology for selection of beneficiation flowsheet is already defined in the above sections. For beneficiation of coarser fraction (+1 mm), jigging is widely usedThe Ka’oje metallurgical grade manganese samples were 44+60BSS), -250+192 µm (- 60+80BSS) and -192 µm (-80BSS) subjected to Jigging and Tabling operations in wet condition for was weighed as feed materials. value addition; owing to great deal of price differences (gains) b) Pulp of 25% solid by weight and 75% liquid (water) by existingResponses of Ka’oje Metallurgical Manganese Ore to Gravity

The Zijin combined gold and copper operation was recently reviewed (Chen et al. 2020) and reported effective bioleaching of low-grade ore with an average grade of 0.43% Cu and a cutoff grade of 0.15%. The Zijin mine was the first commercial copper bioleach operation in China.By 2012, bioleaching became the standard method for low-grade copper sulfide processing, allowing processing of copper feed grades as low as 0.4%. Table 9.1 shows a benchmark of the main operations by 2012 (Enrique Roman, personal communication).
