How a Thickener Works Mineral Processing amp; 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, flatbottomed 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

Next, we mine the resource with hydraulic excavators. During this part of the process, we lay off small pits, approximately 35 acres, and move in a checkerboard pattern. This allows us to move overburden directly into a previously mined pit. We remove fertile topsoil from this overburden during stripping and store it for reclamation.

Overburden is unwanted material on top of sand and gravel, such as glacial sands, clays and peat, which must be pushed or scraped off and stockpiled before excavation can begin. This material is also used in the restoration process. If the overburden is more than five feet thick, it may be too costly to remove.

Wash sand. Sand grains are washed to remove any unwanted silt and clay particles. While the fine silt and clay particles are commonly used for mine reclamation (step 10), sand that is too fine can be sold as industrial sand. Reject material (silt and clay) from the washing process is moved to holding ponds to allow the material to
