The no. 0 prospecting line shows the occurrences of the orebodies (Fig. 2 c). The largest orebody is 1170 m long in strike, 73-250 m in dip direction with an average of 131 m, and a thickness of 1.3-27.7 m with an average of 11.4 m. The proved and inferred W-Mo reserves reached more than 30,000 tons, about 20,000 tons of W and 10,000 tons of Mo.

Cone crushers are suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc. Type of the crushing cavity is decided by the application of the ores. Standard type is for PYZ (secondary crush); middle type is for PYD (tertiary crush); short-head type is for primary and secondary crush.

CRUSHING • Crushing is the first mechanical stage in the process of comminution - it is critical for the preparation of ore for down stream processing. It is generally performed dry in 2 or 3 stages. Large lumps of ore ≤ 1.6m are typically reduced in the primary crushing stage to 0.1 - 0.2m particles. • Factors Affecting Crusher Selection Factors which influence the selection of size ...

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

It presented massive coarse-grained textures with grain sizes varying from few micrometres to more than 1 cm. Scheelite was often finely disseminated and rarely laminated, overprinting sedimentary structures. It formed 5 to 300 µm anhedral crystals with an average size of 150 µm, which constituted the liberation size for the Main Skarn.
