rock gold extraction equipment stlb knelson gold centrifugal concentrator

GENERAL DESCRIPTION:

For rock gold processing plant,Gold  Concentrator is kind centrifugal concentration equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.

Application shows that the recovery can be as high as 99%, especially for the case in recovering the natural gold in lode  ore with 65% of the ore having a milling size of 0. 074mm, the recovery for the natural gold is expected up to 98%.For those natural gold of   0.004mm in particle size, the recovery is 97%.
The cleaning up cycle is 1~4 hours, and the upgrade ratio is up to 1,000 times. The equipment is patented in China.

MACHINE FEATURES:

Knelson Concentrator unit capacities range from laboratory scale to 100 tonnes of solids per hour, and combines centrifugally enhanced gravitational forces with a bed fluidization process to provide unmatched performance in the recovery of precious metals.

Rugged design and a high degree of quality manufacturing ensures that every Knelson Concentrator will provide many years of reliable operation in even the most severe operating environments.

The Semi-Continuous (Batch) Knelson Concentrator has been successfully applied in the recovery of gold, platinum, silver, mercury and native copper. It is available in five models;

TECHNICAL DATA: 

Five models are available. 

HOW THE GOLD CONCENTRATOR WORKS

The Knelson concentrator utilizes the principles of [centrifuge] to enhance the gravitational force experienced by feed particles, which aids in the separation process based on particle density. The key components of the unit include: a cone shaped "concentrate" bowl, which is rotated at high speed by an electric motor and a pressurized water jacket encompasses the bowl. Feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the center of the bowl from above. The feed slurry contacts the base plate of the vessel and, due to its rotation, is thrust outward. The outer extremities of the concentrated bowl house a series of ribs, and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and the heavy mineral particles (usually of economic value) becomes trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated. The Knelson concentrator typically operates as a batch process, with lighter [gangue] material being continuously discharged via overflow and a heavy mineral concentrate periodically removed by flushing the bowl with water.
