  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, 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.

  • Metal Recovery Rate How to Interpreted the Mineral

    The metal recovery rate can be found in a mining company’s National Instrument 43-101 or in a similar applicable international reporting standard. Example: When you read a press release in which a mining company announces a resource of 500 million tonnes of 1% copper and a mineral recovery rate of 80% you should actually read that the company

    Separation may be a simple bulk float (i.e.pyritic gold ores, some copper ore with negligible pyrite) or as is the case for polymetallic ores, a complex three stage sequential separation (ie copper, lead, zinc). the recovery and grade of the last two or three cycles may be adequate for simple process

  • Copper ores Danafloat

    This is related as: 1) iron sulphide mineral levels are usually much higher than copper concentration, 2) sulphide flotation collectors can float iron sulphides well also, 3) liberation can be an issue making copper and iron separation difficult, and 4) fine particles are often more difficult to separate.

  • Copper extraction Wikipedia

    Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
