A first series of tests studied metallurgical recoveries that could be achieved with gravity separation. These tests produced a concentrate grading from 18,158 to 20,968 g/t Au, with recoveries in the order of 50–60% of the gold from the ore. The degree of grinding ranged from 58 to 80% minus 200 mesh; recovery improved as the grind …

The installation in 1948 of a Humphreys spiral concentrator section at the Hill-Trumbull plant of The Cleveland-Cliffs Iron Co. is the latest commercial method on the Mesabi Range being used for the recovery of fine iron ore. In two stages of concentration 84 spirals treat approximately 120 long tons per hour of minus 1/8 in. ore.

This concentrator cant be beat when the job calls for a continuous concentrator for Gold, Glena, Chalcopyrite and Sulfide type hard rock ores. As well replaces Jigs for heavy black sand ores. Fine gold recoverable ability + 90% to 200 mesh in production and 99% above 140 mesh. We stock all spirals and can ship same day as order confirmation!

Weighing just 12 lbs. and measuring 25" long, the Micro-Sluice 2 processes wet or dry concentrates at a rate up to 1/3 cu. yd. per hour. Recovery is typically 98% of visible gold plus 60-90% of free gold down to 200- mesh (tailings can be run a second time to test accuracy). The included high efficiency 1250 gal/hr pump uses only 3 amps x 12 VDC.

The Knelson concentrator (KC) is widely used in gold ore and other precious metal ore processing technology because of its excellent separation performance. The development history and...

The first concentrator is a hopper that is oscillated laterally about 30 - 50 times per minute. ... He had ground black sand to 400 mesh in a small ball mill to release hidden gold values. I assume the material was dry but I cannot confirm this. He then placed the ore in the cup of an ultrasonic jewellery cleaner and turned it on. According to ...

The Knelson concentrator (KC) is widely used in gold ore and other precious metal ore processing technology because of its excellent separation performance. The development history and...

The measurements used for the analysis were the ore size distributions ranging from 14 to 200 mesh (1.20–0.075 mm), the chemical assays (Fe, SiO 2, Al 2 O 3, CaO, MgO, TiO 2, Na 2 O, K 2 O and Fe 3 O 4) of the ore and of the ore within the size intervals of the spiral feed and product streams.

Gravity concentration was achieved with pinched sluices and 76cm Knelson bowls, with a significant increase in fine gold recovery. Again, the first material fills the rings completely. At this point, any similarity in the two centrifugal type concentrators begins to separate as the unit greatly enhances and improves the centrifugal factors.

Tables are efficient to concentrate liberated gold as fine as 200 mesh (0.074 mm), but the efficiency depends on the shape of the gold particles and the uniformity of the grain size fraction. ...
