Technological characteristics of cube extraction of silver

Fang's silver withdrawal technology is mature, advanced, easy to operate, with less investment and quick results.

The biggest feature of Fang Tiyin is that it can add chemical raw materials on site, which can produce precipitation in a few minutes, and then take the precipitation home for purification, which completely solves the problem of inconvenient dispersion and transportation of wastewater. Chemical raw materials can be purchased at local pharmaceutical factories or chemical reagent stores. With this technology, the cost of chemical raw materials for treating 100 kg wastewater is about 50 yuan, and 0.6-2.5 kg of silver can be extracted (depending on the silver content of wastewater). Under the condition of sufficient raw materials, each person can treat 500 kilograms of wastewater every day, and the profit rate is very high.

From June 5438 to February 2006, Fang Xiaoling successfully introduced a new method of extracting silver by hydrolysis. This technology only needs to add a common raw material to the wastewater, and after hydrolysis, the silver powder in the wastewater can be precipitated in a few minutes. Silver powder can be sold directly or simply processed into pure silver ingots for sale. The method is simpler in operation, higher in recovery rate, lower in cost, non-toxic and pollution-free, and can be operated by one person at home.
