Sulfide Ores Flotation

Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a …

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an ...

Flotation of Copper Sulfide Ores 12.5.1 Flotation of sulfide copper ores Sulfide copper ores are considered easy to treat provided that the main copper mineral is chalcopyrite. In case the ore contains secondary copper minerals, such as chalcocite, bornite and covellite, ...

Sequential flotation from gold-bearing base metal-sulfide ores Separation of gold-bearing arsenopyrite from barren pyrite When attempting to concentrate submicroscopic and in particular solid–solution gold, it is important to keep in mind the following two peculiarities of the host sulfides:

Flotation process is widely used to separate these minerals in sulfide ores . A wide range of chemical reagents are used in the flotation process to separate the different minerals. Most of these reagents such as cyanides are toxic in nature and cause detrimental negative impact on the environment [ 3 ].

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le…

pper sulfide ore forth flotation plant - leeuwenloop.nl. 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.

1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Flotation process is widely used to separate these minerals in sulfide ores . A wide range of chemical reagents are used in the flotation process to separate the different minerals. Most of these reagents such as cyanides are toxic in nature and cause detrimental negative impact on the environment [ 3 ].

Flotation of non-sulfide minerals is more difficult than that of sulfide minerals. The main reason is that non-sulphide ores usually have high water solubility, and the useful minerals and gangue minerals are usually of similar types, with a small difference in surface properties.

Compositions including blends of one or more acrylamide/allyl thiourea polymer as a first depressant, and one or more carboxyalkyl dithiocarbamate compound as a second depressant, and their use as depressants in the beneficiation of sulfide minerals from ores and/or concentrates are disclosed herein, along with methods for selectively separating value sulfide minerals from non-value sulfide ...

The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased. Sulfide Ore any of several natural mineral formations consisting of metal sulfides. Metal selenides, tellurides, arsenides, and antimonides are also classified among the sulfide ores. Sulfide ores are an important source for the production ...

Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching.These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using ...
