Shandong 500t/d Copper Lead and Zinc Ore Bulk Flotation Project. Ore Property: Shandong client commissioned Xinhai Mine Research Institute to conduct ore dressing experiment after collected 50kg samples on the scene. After tested the ore properties of sample ore, Xinhai lab concluded that the main metal minerals of the project were copper, lead, zinc, and a certain amount of magnetite.

Factors Influencing Copper Ore Flotation Xinhai

2016-3-1  Copper ore is the mineral mixer containing some copper which could be concentrated by present technology. Sulfide copper is the most common raw material used in mining process plant, because it has a better floatability. Compared with other minerals, there are much more factors influencing copper flotation process. In order to increase copper

Optimization and mechanism of gold-bearing sulfide

2014-6-5  In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process, flotation was adopted based on mineralogical analysis. Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite. The paper describes the effects of ratios and dosage of

Sulphide Flotation an overview ScienceDirect Topics

M.G. Aylmore, in Gold Ore Processing (Second Edition), 2016 5.1.1 Platsol™ Process. The Platsol™ process was originally developed in collaboration with the University of British Columbia, Kane Consultants Ltd., and Lakefield Research in Canada for the treatment of flotation sulfide concentrate for Polymet Mining Company in Minnesota and was tested on similar types of concentrate materials.

The interaction of clay minerals with gypsum and its

2015-6-1  Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.

Silver-rich ores Ores Although some silver-bearing ores contain silver as their largest metal value, virtually none has silver as its main constituent. A typical ore might contain 0.085 percent silver, 0.5 percent lead, 0.5 percent copper, and 0.3 percent antimony. After flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead,
