Silver ore beneficiation process: flotation and cyanidation
Silver-bearing ore is mainly divided into two categories: silver-gold ore and lead-zinc-copper associated ore. Its silver production accounts for more than 99% of the total output. The gold ore beneficiation method mainly uses flotation or cyanidation. The main factor that determines the use of flotation or cyanidation is the composition of silver minerals. When the silver minerals are mainly silver and silver, flotation and cyanidation are all acceptable, but when the ore contains a large amount of cyanogenic minerals such as deep red silver, pale red silver, selenium and silver ore, only Can use flotation.

Lead-zinc-copper associated silver ores have different mineral compositions, symbiotic relationships, intarsia characteristics, and oxidation levels. The sorting results are also very different. However, flotation is commonly used in terms of beneficiation methods. method. In general, the recovery rate of beneficiation of lead-zinc-copper-associated silver ore is lower than that of silver-gold ore, generally between 50-70%.

HUITENG processes 500 tons of silver ore processing equipment on delivery in Morocco

The 500 tons of silver ore processing equipment project for daily processing of 500 tons of silver ore by Henan Xingyang Mining Machinery Factory. It is reported that this project is an EPC project general contract project signed by Henan Xingyang Mining Machinery Factory and its customers in Morocco. As a well-known mineral processing equipment manufacturer in Henan Xingyang Mining Machinery Factory is responsible for the production of a complete set of ore processing equipment for Morocco customers, including: feeders, jaw crushers, fine jaw crushers, vibrating screens, ball mills, classifiers, Flotation machines, mixing tanks, etc.

Features Of Silver ore processing line

1. The crushing system adopts two sections and one closed road, which greatly reduces the grinding granularity of people and gives full play to the role of crushing to improve the processing capacity of grinding. “More broken and less grinding” is the energy saving and consumption reduction of ore dressing plant, reducing costs and improving the economic efficiency of enterprises. One of the effective measures.
2. Grinding a high degree of automation. Through automatic adjustment, it can timely and accurately adjust the amount of change, such as the amount of ore to be added, steel balls to be added, mine water, return sand water, ore discharge water, grinding concentration, etc. in accordance with the measured results to achieve the best Grinding effect, while using grinding automation control, can increase the mill's production capacity. The grinding process was changed from the past closed-circuit grinding to the second-stage closed-circuit grinding, and the second-stage grinding machine used a high-efficiency overflow ball mill to form a closed circuit with the cyclone group. The degree of dissociation of the grinding product is improved, and the quality of the second stage overflow is further improved.
3. The use of new flotation agents to improve the silver concentrate recovery.
