CANATUAN CU/ZN FLOTATION METALLURGY

CANATUAN CU/ZN FLOTATION METALLURGY

+

Commercial copper production was declared on March 1, 2009, when copper concentrate inventory levels surpassed the 5,000 tonne shipping threshold. Increased zinc levels in the ore body, as it was continuously being mined, prompted the construction of a Cu/Zn separation circuit as extension of the previous flotation circuit. The construction was completed in early 2010 following an intensive ...

This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various loions in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then process them using flotation. In this study, the floatability of five types of Cu–Mo ores and ...

purifiion of ores such as copper sulfide ore. Electrolysis uses an electrical current to move ions in an electrolyte solution between two electrodes. In copper electrolysis, when a current is applied, positivelycharged copper ions (called ions) leave the anode (positive electrode) and move toward the hode (negative electrode). In this experiment (Figure 1), a penny acts as the ...

Crushed copper ore is first typically processed via heap leaching. An effective leaching step is critical to SXEW, as it sets the stage for how much copper can be recovered. For this reason, the heap leaching step is commonly preceded by agglomeration of the ore in a rotary drum agglomerator. This offers significant benefits, ultimately yielding improved recovery rates. Agglomeration greatly ...

These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silies and other minerals, called gangue, that will have to be separated. Copper minerals and ...

The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
