The most commonly used jaw crusher wearing parts are: side guard plate and moving jaw tooth plate, fixed jaw tooth plate, bracket, and triangle.In actual operations in mining industry, under the stone material long-term high pressure impact, the body parts of jaw crusher machines are prone to wear and tear. When choosing wearing parts, clients often need to know the body size, type, material and parts. Also, these wearing parts of jaw crusher should be checked at regular. Once they are worn out, they should be replaced as soon as possible.

This requires a balance between metal recovery, processing cost, acid production, and slag generation.5 These trends suggest a dynamic balance between copper mines and processers in terms of defining where to invest and where is the best place to remove each impurity. For example, some Chinese operations have processed low-grade copper concentrates.From the mine processing point of view, the reduction in ore grades and mineralogy changes suggest the need to adapt current mining and mineral processing techniques to maintain production targets of metal units and quality. However, in some cases, opposite strategies have been followed.

Interestingly, oleate can still adsorb onto the H2SO4-treated dolomite surface. The pH of the solution is a vital factor in determining the adsorption state of oleate on a mineral surface [12]. Moreover, the pH of phosphate slurry with H2SO4 is much lower than that in the direct flotation of apatite.H2SO4 cannot prevent the flotation of dolomite with oleate as a collector. The possible occurrence of precipitation of CaSO4 on the dolomite surface is uncertain due to the instability of dolomite in an acidic solution. However, the adsorption state of oleate on the H2SO4-treated dolomite surface has yet to be reported in the literature.
