Oxide copper ore flotation with 800 g/ton sodium oleate at pH 9 yielded % Cu with % recovery in a rougher circuit. To enhance the flotation performance, in terms of %Cu, optimum dosages of sodium silie, quebracho, and pine oil were examined. At the optimum dosages, the grade increased to % Cu with % recovery. To upgrade the rougher concentrate, sodium oleate was added in the ...

INTRODUCTION GoldCopper ores, which require a Dllrumum of two metallurgical processes such as the production of a copper concentrate as a byproduct to recover the copper content of the ore, and, the subsequent cyanide leaching of the flotation residues to recover the remaining associated gold, present, in most cases, processing challenges.
Extraction of Gold by Flotation Process
· (2) Extraction of gold by flotation process is also used to process polymetallic goldbearing ores such as goldcopper, goldlead, goldbismuth, and goldcopperleadzincsulfur ore. For this type of ore, the flotation process can effectively identify and extract various goldbearing sulfide concentrates, which is conducive to the comprehensive recovery of mineral resources.
Flotation of a CopperGold OxideSulphide Ore
Copper recovery is highly sensitive to oxide copper content of the feed whereas gold is primarily associated with the copper sulphide minerals. A conventional flowsheet where sulphide flotation is followed by sulphidization and oxide scavenging is described. The conventional flowsheet was used in a feasibility study which resulted in a favourable production decision at Mount Polley. Detailed ...
Primary Copper Smelting
Pine oils, cresylic acid, and longchain alcohols are used for the flotation of copper ores. The flotation concentrates are then dewatered by clarifiion and filtration, resulting in 10 to 15 percent water, 25 percent sulfur, 25 percent iron, and varying quantities of arsenic, antimony, bismuth, cadmium, lead, selenium, magnesium, aluminum, cobalt, tin, nickel, tellurium, silver, gold, and ...

copper produced in the United States originated from flotation (Daniel E. Edelstein, Copper Commodity Specialist, Geological Survey, written commun., March 20, 2012). Copper sulfide ores must be concentrated before they can be economically transported to a smelter. Froth flotation is part of a copper beneficiation process in which finely ...
Gold Flotation
· This reagent was developed especially for the flotation of oxidized copper ores. The amount of these promoters varies considerably. If the ore is partly oxidized, it may be necessary to use as much as to lb. of promoter per ton of ore. In the case of clean ores, as little as lb. may be enough. The promoter requirement of an average ore will usually approximate lb. Frothers ...
Copper ores
A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and pyrrhotite (Fe1xS). Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range of silie minerals from quartz to talc and clays. Carbonate mineral gangue can also be present. When liberated ...
standarts of copper gold ores flotation
Gold recovery, although important, is not always considered when optimizing the copper ore dressing Britannica Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article ...

Evaluation of sodium isobutyl xanthate as a collector in ...
· The dosage of a collector is an important factor that determines the efficiency of a froth flotation process. The representative sample of the carbonatitic Palabora copper ore ground 45 % passing 75 µm was frothfloated with sodium isobutyl xanthate (SIBX) collector at 60, 70, 80, 90 and 100 g/t dosages. The concentrates and tails were dried and analysed. The results obtained showed that .
