In flotation of gold-containing base metal ores, a number of modifiers normally used for selective flotation of copper lead, lead zinc and copper lead zinc have a negative effect on the floatability of gold. Such modifiers include ZnSO. 4 ·7H. 2. O, SO. 2,Na. 2. S. 2. O. 5. and cyanide when added in excessive amounts.
The recovery of gold-containing pyrite to the copper concentrate is encouraged to achieve a higher total gold recovery provided that a saleable copper concentrate grade is still produced. Mineralogical diagnosis of feed and product streams from the copper flotation circuit have shown that the copper bearing minerals are well liberated
The primary purpose of this review paper is to present the hydrometallurgical processes that currently exist in the mining industry for the treatment of silver, copper, and gold ores, as well as concentrate …
Copper, selenium and other elements are first separated from the copper anode slime by hydrometallurgy; then, precious and base metals are separated by flotation. Many tailings are removed by flotation, which improves the treatment efficiency of separation and recovery of precious metals from the anode slime.
Flotation tests performed after grinding processes with both MS and SS balls in wet and dry conditions were evaluated briefly below for three different dosages of collector mixture in terms of solid-water recovery (Rsolid and Rwater), copper-pyrite recovery and pyrite recovery mechanism.
Process Introduction The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores, base metal ores, copper-nickel ores, platinum group ores and many other ores where other processes are not applicable. Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment, for the …

Different milling conditions, such as wet or dry, and use of different grinding media have a great impact on the flotation performance of sulphide minerals. In the present study, the effects of wet and dry grinding and the use of different grinding media, such as mild steel (MS) and stainless steel (SS), were investigated on a Cu-sulphide ore. The …
The selected processing scheme produces separate saleable gold-silver doré and copper-gold flotation concentrates. ... Locked-cycle flotation indicates that copper-gold flotation results in ...
A comprehensive recovery process for the selective separation and enrichment of copper, zinc and iron minerals from a polymetallic ore was developed, which consisted of copper flotation, zinc flotation, and iron magnetic separation, and the adsorption mechanism of the copper collector Z-200 (O-isopropyl-N-ethyl …
