uneconomic (Muir, 2011). Alternative processes for the treatment of copper bearing gold ores are flotation (Bulatovic, 1997 Forrest et al, 2001), ...
Copper extraction. Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings...
flotation performance (Shortridge et al. 1999; Dalvie et al. 2000). The objective of this research was to determine the level of copper sulphate dosage that can activate the chromite and also to evaluate the effect of the depressant type and dosage on the recovery of chromite in the flotation of UG2 ore. The
Dec 20, 2018· Gold flotation. The Froth Flotation Method is means separating minerals according to their different physical and chemical properties. According to classification, the flotability of gold and silver minerals is included in the first category of natural and nonferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, which can be flotation by xanthate .
Flotation reagents at the Stawell Gold Mine in Victoria, Australia, where carbonaceous pyrite–pyrrhotite gold ores with minor quantities of arsenopyrite are floated at a slightly elevated pH value, include copper sulfate, PAX and Terric 407 frother.
Jul 09, 2019· 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Coppersulfur ore Called copperbearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.
Good Project Recycling Scrap Copper To Copper Sulfate ... Copper sulfate production equipment. By my company after years of research, with purple copper as raw material to produce copper sulphate production technology and special equipment to achieve the perfect level, has the following features: production (24 hours) 10 tons of copper sulfate ...
Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold. Copper sulphate is frequently helpful in accelerating the flotation of pyrite and arsenopyrite.
Copper Sulfate In Gold Flotation Flotation plant. a complex sulphide ore of this type requires a high degree of selectivity in the flotation process. the lead and copper must be removed in bulk as a mixed concentrate and then the zinc . Read More.
Industrial Grade Copper Sulphate . Copper sulfate is used by mining organizations in flotation processes, especially for treating leadzinc and gold metals. It is likewise utilized as a part of some material coloring processess, in the make of specific sorts of rayon strands, in cowhide dressing, as an additive for timber and in hostile to fouling paints.
The copper flotation tailings are the feed to the sphalerite flotation circuit where the zinc minerals are floated as explained in the leadzinc flotation section. Sphalerite is first activated with CuSO4 and floated typically at elevated pH for iron sulphide depression. Combinations of xanthate with either dithiophosphate and/or ...

This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using sodium sulphide, hydrosulfite, lime, cyanide, zinccyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important, even critical, consideration.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. ... Introductions for the Ore Flotation Solutions of the Copper Lead and Zinc 15:39:53 XinHai Views (3385) ... copper sulfate(500g/t),butyl xanthate(60g/t),2# oil( 60g/t), and the ph of the flotation should reach 1213. After the ...
sodium sulfate flotation. Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper lead and zinc minerals in their oxidized form The sulfidization process developed in the USA in 191520 for oxide copper minerals flotation is especially suitable for
Promoter for gold, silver, copper and zinc sulphide ores. Stronger than sodium aerofloat. Aerofloat 208: A nonfrothing water soluble dry aerofloat. 510% solution .01 to .10: Alone or in the combination with reagent 301 is widely used for flotation of gold and silver. Aerofloat 211: A water soluble dry aerofloat. Formerly sodium aerofloat B.
These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits. Supergene ores rich in sulfides may be concentrated using froth flotation.
The metal industry uses large quantities of copper sulphate as an electrolyte in copper refining, for copper coating steel wire prior to wire drawing and in various copper plating processes The mining industry employs it as an activator in the concentration by froth flotation of lead, zinc, cobalt and gold .
industrial copper flotation machine . SF Flotation Machine is the representative equipment in the flotation production, mainly used in the flotation of nonferrous metals and rare metals, such as copper, gold, silver, zinc, lead, nickel, etc; and nonmetal materials, such as kaolinite, phosphorus, sulfur, etc.
May 30, 2016· Different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation. With the BCL SelebiPhikwe ore body, pentlandite–pyrrhotite–chalcopyrite cooccur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited. In the presence of pentlandite, pyrrhotite can even be galvanically depressed.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
The favored thiosulfate leaching conditions were 5 mmol/L copper sulfate and 50 mmol/L ammonium thiosulfate at a pH value of, which allowed less generation of polythionates and their subsequent loading on the resin ( kg/t). Gold and copper loadings .
copper ore gold flotation cell grinding ball mill manufacturer; ... Machine Grinding Mill manufacturer supplier in China offering Copper Gold Ore Grinding Ball Mill Ball Grinding Mill Copper Sulfate Mining Flotation Machine Longer Service Life Double Stage Wet Coal Gangue Crusher and so on.
Gold with transition elements, such as silver (gold–silver alloy), copper (copper aurides) and iron are common in most of the hypogene and altered copper–gold ores ( supergene). The distribution of gold in an ore plays an important role in the selection of the type of flotation process that can be applied to recover the gold [34].
