Russell Jig Brochure
Russell Jigs can be used as either primary, secondary or tertiary concentration devices. When used as a secondary or tertiary Jig, the throughput rate should be reduced to approximately 1/3 to 1/2 for a secondary and 1/4 to 1/3 for a tertiary, of the primary rated capacity. This will ensure maximum recovery and minimum concentrate volume.

Since1985, three models have been developed. 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 milling size of 0.074mm,the recovery for the natural gold is expected up to 98%. For that natural gold of 0.004mm in particle size. The recovery is 97%.

Titanium Ore Processing and Beneficiation
¾" crushed ore passes through a peripheral discharge Rod Mill at high dilution (35 to 40% solids). This minimizes over-grinding and sliming of the feed particles of titanium. The peripheral discharge product from the rod mill is elevated to a Duplex Mineral Jig making a rougher heavy mineral concentrate for retreatment in a Simplex Mineral Jig.

Ask MGS: What are Gold Concentrates?
Gold concentrates tend to be mostly iron, so they are also known as "black sands.". Gold concentrates are also made by grinding down ore, quartz, or other productive rock types into sand. This procedure is much faster and easier than panning, but the tradeoff is a final product that has less gold "concentrated" within.

Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 – 0.1)/(2.09 – 0.1) = 10 So, for each 10 tons of feed, the plant would produce 1 ton of concentrate.
How To Extract Gold From Sand?
In gold sand gravity separation, when roughing with a chute or jig, the coarse concentrate is usually enriched by a shaker with a very high ore ratio, its recovery rate can reach more than 98%, and directly get the final concentrate and abandoned tailings.
