Flotation experiment research on a polymetallic sulfide ore of ... The most valuable elements in a polymetallic sulfide ore in the Shanxi province are copper, lead, zinc, gold and silver, and the main metal minerals are galena, sphalerite, chalcopyrite, pyrite, and so on. ... The polymetallic separation flowsheet of copper/lead bulk flotation ...
Clay depressant in a gold and copper bulk flotation plant trial. In production at a Gold and Copper flotation circuit the use of PIONERA F100 showed a recovery increase in gold of 5% and a positive effect on the copper recovery by successfully depressing clay in the bulk flotation process.
The paper presented outlines the scientific approach taken to improve the metallurgical efficiency of a modern plant at Athens Mine. The plant is based on the CIP method of gold recovery with copper concentrate as a major byproduct. In the early stages of the operation the overall gold recovery achieved averaged 61% and copper recovery was 74%.
Flotation combined with cyanidation of the flotation cleaner scavenger tails and the concentrates from flotation of coarse particles from rougher flotation tailings can be used to recover 82% of the gold and 87% of the copper into coppergold flotation concentrates and dore.
gold in copper rougher flotation tailings (% Cu, /t Au, tail grades). An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotation. Also, different collector
Natural pH is recommended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation .
Flotation will frequently be used when gold is recovered in conjunction with other metals such as copper, lead, or zinc. Flotation concentrates are usually sent to an offsite smelting facility for recovery of gold and base metals. Cyanide leaching is frequently used in conjunction with flotation. Cyanidation
Copper–gold ores are significant contributors to the overall world gold production. Flotation is the principal process for preconcentration of the copper–gold minerals for subsequent smelting treatment. Gold recovery, although important, is not always considered when optimizing the copper circuit.
Mar 22, 2017· Mount Milligan is located approximately 90 miles northwest of Prince George in central British Columbia, Canada. The Mount Milligan Mine is a conventional truckshovel openpit copper and gold mine and concentrator with a 62,500 tpd design capacity copper flotation processing plant.
Designed to operate across a broad range of alkalinity levels and provide faster flotation kinetics, our flotation collectors have become the industry standard in the recovery of copper, gold, molybdenum and other metals.
About Eriez Flotation Division. Formerly known as Canadian Process Technologies, Inc. (CPT), EFD is a wholly owned subsidiary of Eriez Manufacturing Co. Since acquiring CPT in 2007, Eriez provides advanced testing and engineering services in addition to sparging and column flotation equipment for the mining and minerals processing industries.
Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and ...
The vast majority of polymetallic sulphide ores containing gold and silver are treated by this method. When flotation of such ores, gold and silver enter into the copper concentrate or lead concentrate closely associated with them. The products are called copper, gold and silver concentrate or lead, gold and silver concentrate, etc.
Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern world would be much more expensive.

The Elverdton CopperGold Mine ceased production in 1971 due to low metal prices, having produced 786,835t of ore for 14,250t of copper and 22,843oz of gold with silver credits. Location and Access: The Elverdton CopperGold Mine is situated about 11km southeast from Ravensthorpe, which is about 530km southeast from Perth, Western Australia ...
Pine oils, cresylic acid, and longchain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarification and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium,
Since February 2017, due to lower grades of gold and higher copper in the feed ore, the decision was taken to alter the flow sheet and to carry out flotation ead of agitation leaching, to reduce ...

Apr 17, 2016· Gold with Lead and Zinc Minerals Gold occurring with leadzinc sulfide ores or copperleadzinc ores usually is recovered into the flotation concentrates and shipped to a smelter where gold recovery is high, particularly at lead smelters. Occasionally, free gold may be recovered by amalgamating the concentrate from a jig in the grinding circuit.
The concentration of gold in the majority of largescale copper/gold ores is low, typically around 12 g/t3,4. Flotation is the principal method of preconcentration for copper and gold5,6. Thus, porphyry copper ore concentrators are designed with the goal of maximizing copper recovery and grade; however, gold recovery as a byproduct is also
Nov 19, 2011· A custom mill in MT, USA milling gold and silver ore through: Jaw crusher, Cone Crusher, Ball Mill, Jig, Shaker Tables, and Flotation Cells. This mill is capable of milling gold, silver, copper ...
Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
The silver content of about 16 ounces occurs as native silver globs, wire and the mineral argentite. After flotation of lead and zinc concentrates, the tailings are cyanided for gold and silver recovery. The great Huelva pyritic copper deposits of Spain carry a little gold and silver.
