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.

2007-5-1 1.. IntroductionCyanidation is the method applied for recovery of gold from ores for a century. New cyanidation processes based on the recovery by adsorption to activated carbon of leach solutions containing low-grade (concentration) gold have been developed since 1970s and 85% of gold recovery is accomplished with this technique today (Gönen, 1992, Hendrix, 1994, Örgül and Atalay, 2002).
