Gold CIL plant in Sudan
Yantai Rhyther offers gold ore concentrator EPC services for the Sudan River Nile province. The mine’s daily processing capacity of ore is 1500 tons, by the Rhyther laboratory for the determination of ore properties, mineral processing experiments, get the following conclusions: the ore is gravity tailings, metal minerals accounted for 3% of crude ore, non-metallic minerals accounted for 97%, recyclable metal for gold and a small amount of silver, gold in the gangue minerals in fine particles and ultrafine particles, gold grade 7.23g / t, silver grade 4.58g / t, leaching rate of 93.21% by the whole mud cyanide gold.
The main configuration of the plant includes:
Re-election tailings by the forklift into the ore warehouse, transported by a belt conveyor to a round vibrating screen, in addition to impurities. And then transported by the belt conveyor to the powder ore storage.
In the whole process of the implementation of the project, Rhyther’s important principles: comprehensive planning, rational distribution, protection of the environment, safe production, strict control of the construction cycle, to provide customers with high-quality plant turnkey service, and get the customer’s approval.
Grinding grading process: the use of two-stage closed-circuit grinding process, the ore grain size reached -200 mesh accounted for 90.0%, and then cyanide leaching. Qualified grain size before the debris and then into the concentrator for concentration.
Cyanide leaching gold extraction process: cyanide leaching carbon adsorption process, designed 8 leaching adsorption, the entire consumption of low doses, access to higher leaching rate. Activated charcoal from the last slot to join, and gradually move forward a slot to get a certain grade of gold charcoal, the charcoal will be added.
Smelting process: The use of wet smelting process, in conjunction with the fire process, the electrolysis after the gold mud into the smelting workshop, will get 99.9% gold.
Tailings dry discharge: Because the mine muddy is serious, there’s higher mud content, after the leaching of the tailings first into the mixing tank, adding flocculant, to a certain concentration, transported to the belt vacuum filter, the solid-liquid separation, get less than 20% moisture dry ore. Filtrate recycling, to achieve zero discharge of sewage.
