Types of ores that can be concentrated by froth flotation method are sulphide ores. Examples are PbS (sulphide galena) and ZnS (zinc blende).

Froth flotation is a process for selectively separating of 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.

Flotation is a term used in physical science to describe when something is suspended at the top of a liquid, like a wooden canoe on water.

Flotation costs are costs a company incurs when it issues new stock. Flotation costs make new equity cost more than existing equity. Analysts argue that flotation costs are a one-time expense that should be adjusted out of future cash flows in order to not overstate the cost of capital forever.

• In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.

• Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter.

• Oxidic ore can be concentrated using flotation or, if it has a low acid demand, it may be economic to acid heap leach the stockpile. The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance.

• Larger plants generally will incorporate a circuit for molybdenum recovery from the copper concentrate by flotation. “Sub- A” Flotation is standard for this service. Crushing Section. The crushing section with two-stage reduction is suitable for smaller tonnages, depending on the ore characteristics.

Then, a cascaded recognition method for copper rougher flotation working conditions will be present in Section 3, which include the overall strategy of method, data fusion framework, identification model of feeding ore types and the recognition model of rougher copper flotation working conditions.

Therefore, after discussed with client, Xinhai adopted two stage closed-circuit crushing, one stage closed-circuit grinding, middlings regrinding, copper lead bulk flotation - zinc flotation - copper lead separation process. Copper lead bulk flotation adopted a roughing, three scavenging, four cleaning process.
