The conventional treatment of copper–gold concentrates involves smelting, converting and electrorefining to produce a coppercathode product. Sulfur in the copper
One of the trends in mining and mineral processing has been to optimize the economics of the mining and milling operations in concert the “minetomill” concept.

Metallurgical testing is the most essential part of any mineral processing flowsheet development. Its objectives must therefore be clearly defined. These are discussed
Copper and gold have similar cyanide metallurgy depending on the nature of the minerals present. The processing of gold copper and copper gold ores can be highly problematic,
Figure 1 shows an example of the most common porphyry copper ore type beneficiation flowsheet. Porphyry ores, although generally contain small amount of copper below 1%,
determined. In general terms, mineral processing operations have % that oscillates between 2% to 10%. This paper provides a robust methodology to quantify

A much more difficult mineral processing challenge is the selective flotation of arsenicbearing copper minerals (e.g., enargite, Cu 3 AsS 4, and tennantite, (Cu, Fe) 12 As 4 S 13). These minerals have
Instead, these reviews are focused on possible options for future development (Sole et al., ), on only the mineral processing (Shengo et al., ), or on design considerations The second generic flowsheet starts with the flotation of copper and cobalt minerals. The concentrate is then roasted to a calcine, which is then treated
Albion Process™ has realworld success in delivering consistently high recoveries up to 97% in refractory gold and over 99% in chalcopyrite copper concentrates. It has much lower capital cost than traditional leaching plants like pressure oxidation (POx) plants and because it operates at atmospheric pressure, it completely avoids the
Table 1 shows that the ore contains 0.53% Cu, 1.29% Pb, and 0.53% Zn; the gangue components mainly are CaO and SiO 2; some gangue material will float to the mixed concentrate with useful

Weiss 4, power consumption in mineral processing accounts for half of operating costs. For process plants that include both mineral processing and downstream . processes, the capital cost of communition represents between 20% and 50%. These figures underscore the value of simulation in process optimization, and in selecting and sizing
Flotation of nonsulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then
Copper processing techniques are evolving to unlock complex, lowgrade deposits and speed the funding and permitting of projects vital to the energy transition. By Carly Leonida, European Editor. The drivers for innovation in copper processing are firmly grounded in the macrotrends that are reshaping the global economy. According to Wood
On the rough flotation copper minerals and pyrite are collected, then in three stages of cleaners is obtained final copper concentrate. The process of flotation takes place in a flotation cell of

Silverrich ores and copper sulfide ores: Silverrich ores and copper sulfide ores are often freemilling, but when the silver grade is high (>10 g/t) and/or the gold is present as electrum, the processing may need to be modified. The greater reactivity of silver SGS MINERALS TECHNICAL BULLETIN 200403

The Boddington copper gold ore is of similar rock competency to that selected for this study and thus provides a good contrast between comminution processes designed to liberate minerals for flotation, in which the whole ore is ground to fine size, and the comminution process with the staged rejection of silicates.
