The Know-How or Experience is on gold-loaded carbon elution and pregnant solution electrolysis, for direct production of  gold alloy. It is maily learning for small scale gold mine,  which adopting carbon in pulp plant or heap leaching, which adopting  active carbon adsorption process. It will help the small scale gold mine to get the pure […]

This lead and zinc ore dressing plant adopt flotation method. The capcity is 600t/d for one line. The equipment includes 2 sets of grate ball mills and spiral classifiers, 24 sets of mechanical agitation flotation cells, 4 heavy duty agitation tanks. This kind of design is simple (little wear parts), robust, high working efficiency,  low […]

   Choose the proper size ball mill and hydrocyclone according to the ore charactor and the processing capacity.  Adopting the slurry pump with frequency conversion feature to feed the hydrocyclone for easy adjustment  Install Particle Sizing Systems to test the hydrocyclone overflow particle size easily  Make the feeder hopper, ball mill, slurry pump and hydrocyclone […]

In the laboratory of mineral processing, we always need to crush the ore in the proper size for the operation of grinding or analysis test. We could adopt jaw crusher as primary crusher and double roller crusher as the secondary for this job. The finished product size after crushing will be 1~3mm. And the capacity […]

In  the modern new material laboratory for research semiconductor or metallic material, we always face to crush the super hard material with compressive strength more than 250 MPA such as the SiC, or alloy (up to extremely 3900MPA). It is a problem to crush these material by the tranditional type jaw crusher. Why the traditional […]

Fineness is the operating index of the grinding and classification process of the ball mill, and the fineness of the discharge and classifier overflow and coarse sand return should be measured frequently in the ore dressing plant or froth flotation plant in order to adjust the operation in time. The rapid sieve analysis method commonly […]

In order to make the Electrowinning pilot plants to be versatile, we have to consider the 5 elements. No.1,  the material of electrolyte solution. You adopt the aqueous solution system or molten salt system. Here we just focus on the aqueous solution system, by which we could get the follow metal to be electrowinning: Cu, […]

In fact, the product discharging size depends on the gap between fixed jaw plate and moving jaw plate. We also call ” the gap between fixed jaw plate and moving jaw plate ” as CSS (Closed Side Setting). But the CSS (Closed Side Setting) is not the finished product size. If you set CSS of the […]

In mining and mineral processing industry, the filter press is always for dewatering the froth flotation concentration or the tailngs. It is very important to choose a proper slurry pump for working with the filter press to get the best dewatering result. First step,  Let us review the working principle of the filter press The […]

In mining and mineral prcossing industry, there are 2 kinds of Laboratory Ball Mill–Continuous type and Batch type . They are all wet grinding ball mill. It is easy to adjust the discharging particle size. 1. Continuous Ball Mill. It likes a small closed circuit grinding plant. It consists of feeding hopper, feeders, ball mill, […]
