In froth flotation of sulphide ores, the material that floats is the specifically the heavier part. This fact excludes the hypothesis that the overflowing solid in the bubblecolumn cell is lifted by the rising fluid current induced by the air bubbles.

This paper is aimed at a typical complex polymetallic copperzinc sulfide ores in Yunnan province, China, and adopted the process of bulk floatation discarding tailing under coarse grinding condition, the influence factors are researched such as grinding fineness, types and dosage of flotation reagents.
In the sulphide or telluride ore, the gold is chemically combined with tellurium, The ore from the Fimiston Open Pit and Mt Charlotte Underground Mine is creating mudlike slurry which is pumped to large tanks called flotation cells.
Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant.

Grinding mills liberate the ore from the gangue material (nonores: silica, organics), and reduce it to an optimal size for flotation. Water mixes in to form slurry. This helps both in the transportation and separation of the solids.
When planning a new flotation plant design, simulation models can be used to design the circuit configuration and cell sizing. In both cases the models are based on experimental data from the minerals flotation kinetics.

dosages of SHMP have little impact on pulp rheology at 40 wt % of slurry, but there is a huge difference on flow property at 20 wt % pulp. The results revealed that rheology, which is caused by ... as well as different particle size data. Flotation tests were conducted at 40 wt % pulp and 20 wt % ... Key element composition of sulfide ore ...
zinc ore is more difficult than that of corresponding sulfide mineral, due to the lack of natural flotability of smithsonite caused by chemisorbted water molecules on mineral surface [5]. Another major problem in processing smithsonite is the large amount of ultrafines and slimes,
There are too many variables involved in a flotation process for a onesizefitsall approach to be effective, so an Axis House solution is tailormade for the application," he says.
B. Processing of Sulfide Ore Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2 ...
The reported effects of the grinding method and grinding medium upon the flotation performance of sulphide minerals has shown that the pulp chemical environment, the ore composition, the properties and type of the grinding media, the size reduction method employed, preconditioning stages prior to flotation, and reagent interactions during ...
A flowsheet for treating flotation concentrates produced from lowsulfide platinumcontaining ores has been developed. It provides low consumption of cheap reagents, complete water circulation and gives a high recovery of platinum group metals and nonferrous metals into rich concentrates.
Recovery of Gold in Pyritic Sulfide Ores The now extinct Us Bureau of Mines conducted numerous studies of gold in pyrite, and sulfide ores over the years, until their untimely demise in the 1990's.
form of waterbased slurry) is transported to the flotation circuit where the copper sulfide ore minerals are concentrated and separated from the nonmineralized material by a series of rougher (see fig. 3) and
The use of ozone during certain stages of metal separation by flotation degrades certain collectors that are absorbed on the particle surface, as well as the collectors and frothers in the liquid slurry. As a result, the mineral particle has a fresh surface and new chemical reagent(s) can be added in the subsequent flotation step(s). Also since ozone oxidizes the iron sulfide particles faster ...
