Introduction to the processing technology system of the jaw crusher production line

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Sand production line

Sand production line processing technologye

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Mineralization of cyanide originating from gold leaching ...

2020-1-3  Although gold leaching can be performed using solutions with relatively low cyanide concentrations (100–500 mg L −1) [3, 4], most mining companies use sodium cyanide in excess.The problem is that leaching is not a selective process and cyanide can react with different metals existing in the ores (e.g., mercury, zinc, copper, iron, and nickel) forming various complexes.

How does the Cyanide heap leaching process work and

2021-4-2  Cyanide leach mining is a type of gold mining that uses cyanide to extract gold from the surrounding rock. First, the rock that contains gold (the ore) is dug out of the ground, leaving behind a large open pit. Then, the ore is crushed into small pieces. The crushed ore is placed in large piles, called heaps, and sprayed with cyanide solution.
