Single mineral flotation tests were performed to evaluate the flotation behavior of chalcopyrite and pyrite using HEDP or EX as collector at a dosage of 2 × 10 −4 mol/L with the results shown in Fig. 1(a). It can be seen from Fig. 1(a) that, within the pH range studied, the flotation recovery of chalcopyrite using HEDP as collector was slightly higher than that of chalcopyrite with EX as ...

Get PriceThe flotation process and related flotation cells are widely used for treating metallic and nonmetallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. Practically all the metallic minerals are being recovered by the flotation process and the range of nonmetallics ...
Get PriceFlotation as a method of separation is widely researched and is applied in many industries. It has been used to address a wide range of environmental issues including treatment of wastewater, recovery of heavy metals for recycling, extraction of minerals in mining, and so forth. This laboratory attempts to show how such a simple method can be used to separate chemicals and minerals.
Get PriceZinc is mostly extracted from oxidized zinc and zinc sulfide minerals, and this process involves flotation as a key step. While it is easier to float the sulfide mineral, its consumption and depletion has led to an increased reliance on oxidized zinc minerals, including smithsonite.

Get PriceFlotation is used to separate sulfide ores from the impurities in the ore . A detergent is added to the mixture and it is stirred. The sulfide minerals float, while the gangue sinks to the bottom and is removed. This is used in making zinc, where zinc sulfide is a major zinc ore.
Get PriceThe flotation of molybdenite seemed to be less influenced by xanthate than by kerosene, while that of chalcopyrite showed the opposite. The optimum concentration of sodium sulfide for separation was mol/L, which rejected 83% chalcopyrite and recovered 82% molybdenite in the single mineral flotation.
Get PriceThe similar flotability of scheelite, fluorite, and calcite resulted in the difficult separation by flotation. This work revealed the effect of water glass on the flotation of scheelite by FTIR and the wettability change of the usual cleavage plane, and proved that water glass inevitably influenced the flotation of tungsten minerals to a large extent in traditional fatty acid flotation process.
