froth flotation equipment for gold ore

gold processing

The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below). These heaps …

Copper mining in the United States

In the 1910s and 1920s, copper mills adopted the froth flotation method, which had been developed in Australia. Whereas the old gravity methods of concentration, using jigs and tables recovered 60 to 80 percent of the copper in the ore, froth flotation recovered 90 to 95 percent. The Bingham Canyon mill installed froth flotation in 1918.

Mineral separation is dependent on both reagent chemistry and water chemistry (Fuerstenau et al., 1985). Flotation equipment (cells) provides the mechanism for air (as bubbles) to come into contact with mineral surfaces so chemical attachment can take place for separation of the selected mineral species.

Types of Mine Waste and Disposal Methods

Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock, or overburden, must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, the additional waste rock will be removed to get to the actual ore, called gangue.

Stamp mill

A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.
