thickener process in mining

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Stone production line

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Concentrate Thickener Operation - 911 Metallurgist

12/08/2015  The thickener is a very basic piece of machinery that performs its job in an easily understood manner. It simply provides a holding area large enough to allow the concentrate time to settle to the bottom. Once there, there are RAKES that rotate pulling all of the mineral to the center of the thickener. Prom that point it is pumped to the filter. The excess water that is not wanted in the concentrate is allowed to flow over the side of the thickener

Thickener Optimization in your mining process

The thickening process is a fundamental step in modern mining separation processes. Thickening is the separation of suspended particles from a liquid by gravity settling. For effective thickener control, six measurements are critical: bed mass inventory, bed level, underflow density and flow, flocculent dosing and overflow clarity.

How a Thickener Works - 911 Metallurgist

13/07/2016  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 ...

This thickener is indepently developed and successfully designed by Xinhai. The internal deaerating tank and serrated overflow weir prevent solid particles from adhering to bubbles, improve local suction phenomenon and greatly increase the sediment space; At the same time, Xinhai changed the traditional horizontal feeding to inclined feeding, which fundamentally eliminated the feeding jams.

In the current ore dressing process, most mineral processing plant adopt wet separation process, so the concentrate has very high water content, which can't be smelted directly. As the first step of dewatering operation, thickening operation occupies 9% influences on the whole beneficiation process, and 35% effects on the whole dewatering operation.
