The most common concentrate extraction techniques are flotation and leaching that have greatly increased the ability to process low grade ore bodi The waste ground rock and the spent processing water and reagents from the plant are known as tailings The word tailings is sometimes applied to include coarse mine waste
The invention belongs to the field of mineral processing, relates to a beneficiation method, and particularly relates to a method of sorting copper sulfide ore flotation tailings The method comprises the following steps: A, the tailings with copper and sulfur separated are dewatered through a thickener, wherein the content of the sulfur in the tailings is more than 20%, and the concentration .
DESCRIPTION: Flotation with cyanidation of flotation tailingsThis flowsheet has a gravity gold recovery embedded into the grinding circuit’s ball mill discharge ORE TREATED: Ores containing both oxide and sulphide minerals with gold or silver, or those ,
Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990)
copper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings As is typical for flotation tailings containing silicate gangue minerals, high temperature leaching was used 
A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial The flowsheet in this study illustrates a typical 3,000 ton per day operation , The tailings or middlings from the flotation cleaning circuit can .
Copper Sulfide Flotation Circuit Cleaner flotation tailings are returned to the head of the rougher flotation circuit for retreatment In many milling circuits, particularly if coarse grinding is used, the cleaner tailings will contain middlings or mineral with attached particles of gangue Summary of Porphyry Copper Sulfide Processing
efficiency of copper and nickel from the flotation with high preconcentrate s-sure oxidative leaching (HPOL) A comparison was made between the leaching efficiencies of copper and nickel from flotation concentrates and mine tailing Keywords Mine Tailing, Flotation, High Pressure Leaching, Copper, Nickel 1 Introduction
Dewatering of Copper Flotation Tailings: Effect of Feed Dilution on the Thickener Performance Mohammad Reza Garmsiria and Ataollah Nosratib aYoung Researchers and Elite Club, Sirjan Branch, Islamic Azad University, Sirjan, Iran; bSchool of Engineering, Edith Cowan University, Joondalup, WA, Australia ABSTRACT Aqueous slurries’ dewatering using gravity-driven thickeners is an essential unit .
The concentration of sulfide copper minerals by means of flotation generates large volumes of tailings It is estimated that one hundred twenty-five tons of tailings are generated per one ton of produced copper, and its generation is on a continuous rise because of the decrease of the copper grades On the one hand, the tailing is considered .
Evaluation of tailings from processing plants is always an important issue Lead-Zinc ore tailings containing 312% Zn, 343% Pb, 071 g/t Au and 74 g/t Ag was subject to this study
