inch knelson concentrator

A gravity circuit has recently been installed (October 2006). A stand alone 30 inch Knelson Concentrator is fed by each of the running mills and recovers gold concentrate from the mill discharge sump. This concentrate is further enriched on an automated Gemini table and then smelted to produce gold bullion.

The results of the batch amenability tests using the 3-inch laboratory Knelson concentrator (LKC) are summarized in Table 3. The concentrate from the first LKC-panning stage recovered 15% of the gold in 1.3% of the total mass and graded 14.65 ppm Au. Although the weight of the concentrates from the following stages remained relatively stable ...

The 3-inch KNELSON™ centrifugal concentrator plus Vibrating Screen proved effective to use in the laboratory. Calculation of unmined gold reserves in Mongolian placers is more complicated than previously thought. As well as the major issue of gold losses to the tailings, the issue of systematic underestimation of the original reserves is also ...

tests were conducted using a laboratory size 3-inch Knelson centrifugal concentrator, on 3kg batches at a feed size of 80% passing 212µm. The gravity concentrate produced was then amalgamated with mercury in a bottle roll for two hours to recover free liberated gold with the amalgam tail then intensively leached.

Knelson concentrators have proven to be extremely successful in gold plants within Australia, where free gold exists in the grinding circuits. In January 1993. a full-scale plant trial using a 30-inch manual discharge Knelson concentrator was commissioned. In …
