Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process .It is a high technological enterprise that integrated research, manufacture, sales and service . The company has multiple subsidiaries such as Mineral ...
Abstract This study focused on the development of a new method, regrind–flotation pretreatment, to improve the performance of the CIL (CarboninLeach) circuit at copper–gold concentrators. Occlusion of gold by iron sulphide gangue minerals and the fine grain size of gold associated with them contribute to the low gold recovery in the CIL circuit.
flotation flowsheet might include rougher flotation followed by scavenger flotation. The rougher and scavenger concentrates may be reground to a F roth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper.
flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85% of chalcopyrite can be recovered with a copper grade of % in a singlestage froth flotation. The chalcopyrite flotation concentrate can be sent back to chloride leaching circuits.
GOLD AND SILVER PROCESSING. EFD has a number of industryleading flotation products for processing gold. This includes the HydroFloat, a stateofthe art flotation unit that uses fluidization to selectively float coarse and high SG gold particles that cannot normally be
How to calculate grade and recovery concentrate? Location: Home >> News >> Profession news In the process of ore dressing percentage, the percent of quality of a product obtained and quality of raw ore, known as the yield rate of product.
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 .
In this study, experiments were carried out on copper ore containing gold and silver obtained from Kisecik village of Hatay, which is in the south of Turkey. Analyses of original ore showed that the sample contained % Cu, % Co, % Zn, ...

Copper flotation is a main method of extraction of copper. With 20 years of experience, Xinhai put much attention to copper processing, formed its copper flotation process.
Improving copper flotation recovery from a refractory . Lime is commonly used as a pH regulator and depressant against iron minerals during the flotation recovery of copper minerals from copper porphyry sulfide ore. It can also depress copper oxide, secondary copper sulfide or gold minerals ( Allan and Woodcock, 2001, Sun, 2001, Liu et al ...
Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.
Oct 25, 2018· The aim of this work was to extract gold present in flotation tailings, but also other valuable metals from flotation tailings by cupric chloride leaching. Experiments were conducted to determine the effect of cupric and chloride ion concentrations on the dissolution of gold, copper, nickel, cobalt, zinc, and iron.
2. 2. Flotation Procedure All the flotation testwork was done using the Denver laboratory machine with a stainless steel flotation cell. The required mass of nickelcopper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. .
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.
