How a Thickener Works Mineral Processing & Metallurgy

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were

mining Mining Methods The method used to mine a specific commodity depends chiefly on the shape and location of the deposit. In many instances, the deposit is relatively flat and continuous over a large area. Examples of flat, or tabular, deposits are those of coal, potash, salt, and oil shale. These deposits are found in beds, or seams, between layers of rock.
