Flotation of this superfine feed was conducted in the same conventional subaeration flotation cell. Aerofroth 71 was used as a frother for talc whereas soda ash was tested as selective depressant of carbonate. In the meantime, quaternary amine was employed in the laboratory as a selective collector for talc. 3. Results and Discussion. 3.1.
The ore is a sulfide copper ore containing heads of approximately copper 0.45, iron 3.5, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the flotation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb.ton.

The known method of flotation of copper-molybdenum ore beneficiation, including collective copper-molybdenum flotation in an alkaline environment, created lime. The bulk concentrate is treated with oxygen at a temperature of 60-95 C., a pressure of 0.05-1.0 MPa and pH11,0 selective flotation of copper and molybdenum concentrate emitting ...
In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03 copper, 0.15 cobalt and 3.73 sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant.
the flotation recovery of Ni, Cu and Co from a nickel-copper sulphide ore. The effect on flotation performance of various parameters such as pH, collector dosage, solids and depressant dosage at different levels was investigated. Therefore, the main objective of the study was to optimize the process parameters for the flotation of base metals ...
The rougher flotation behavior of a sulfidized copper ore was studied by a series of batch flotation experiments. Response surface modeling based on central composite design was applied to optimize and evaluate the effects of collector, depressant and frother dosages, solution pH and agitation rate on the copper recovery.
copper-molybdenum ore beneficiation,flotation separation. This article discusses the beneficiation method of copper and molybdenum ore and the separation process of copper and molybdenum. 1.Status of copper-molybdenum ore beneficiation Based on the overall structure of porphyry copper-molybdenum deposits, there are usually three types of minerals in symbiosis, namely copper, molybdenum
The testwork discussed in this paper was performed for a copper-molybdenum operation that is experiencing coarse particle 150 m losses in the tails. This operation uses Diesel No. 2 fuel and sodium ethyl xanthate for molybdenum and copper flotation, respectively and X-133 frother.
Jul 28, 2016 In this paper, prediction of copper and molybdenum grades and their recoveries of an industrial flotation plant are investigated using the Artificial Neural Networks ANN model. Process modeling has done based on 92 datasets collected at different operational conditions and feed characteristics. The prominent parameters investigated in this network were pH, collector, frother and
sodium ethyl xanthate for molybdenum and copper flotation, respectively and X-133 frother. In an attempt to increase coarse particle recovery, stronger collectors potassium amyl xanthate, Aero 249 and Aero 3501 and frothers FrothPro 618, FrothPro 630 and FrothPro 706 were used. The analysis was

Oct 01, 2017 A coppermolybdenum iso-flotability flotation process has been developed to efficiently improve the recovery of molybdenite from Duobaoshan porphyry CuMo ores. The effects of flotation approach, type of collector, feed particle size distribution, rougher pH value and reagent dosage on the recovery of molybdenite were evaluated systematically.
Flotation is one of the most widely used techniques to separate valuable minerals from gangue minerals in the mineral processing, because of its ability to treat low-grade and complex raw materials in the fine particle size ranges 3,4,5,6,7.Froth flotation takes place in the presence of three different phases, including solid particles, liquid water and gas air bubbles.
MINING Copper-Molybdenum ores Molybdenite MoS 2 is the predominant economic molybdenum mineral. While naturally very hydrophobic and can effectively be oated with just frother addition of a hydrocarbon oil extender enhances its recovery. Making very pure moly concentrate grades is necessary for lubricant and oil additive appli ions so the ...
