Production of accompanying gold (commodity concentrates) by using new technologies of enrichment from sands (tailings) of current manufacture and dumps on working ore dressing intergrated works without infringement of the technological operating of the basic production

VIMS and AOZT "Converse-gold" have developed, made and tested industrial samples of a sluice with vibrating travelling panel under working conditions on the first stage of enrichment allowing to extract fine and thin gold (0,02 mm) with high productivity (up to 80 м3/hour on solid) and low capital and operational expenses in comparison with other technologies. The construction is defended by patent of R.F.

Free (gravitational) gold with contents from 0,02 to 1,5 g/m³ and more was determined in running sands, products of process stage, tailings of working State Concentrating Mills, developing deposits of the sandy-gravelly mixtures,phosphorites, iron ores, titanium-zirconium places, and also in moving mountain masses.

The industrial interest is represented by the enterprises with wet cycle of enrichment with productivity higher than 200 m³ of sand (tailings) a year with minimal gold content 70 mg/m³ in sandy fraction. On the territory of only European part of Russia Tens of similar working objects are known. Development works are conducted in Mikhaylovsky, Vyazemsky and Khramtsovsky State Concentrating Mills.

Offered program, realization of which will allow to adjust production from current output on specific State Concentrating Mill (from 0,5 up to 1,0 and more) tons of gold a year at the cost of 1 g 3-4 $ US during 1-2 years (the world price 9 $/gr). Reccupment of investments with minimal contents and volumes is 1-1,5 years.Whith contents higher than minimal ones pay-back periods are considerably reduced . Volumes of the investments in each object from 200 thousand to 6,0 mln. $ US depending on output of the basic production

• Choice and estimation of perspective object,
• Production tests with the purpose of adaptation the equipment in real production and working out the technological rules,
• Organization of production on passing gold extraction up to design output for annual volume of the current sand (tailings) by full technological cycle.
