If the material contents too much water, it would cause the materials accumulation in the crushing chamber, and lead blockage phenomenon, that not only increase the wearing of the parts, bur also reduce the service life of the machine.and the feeding speed should be evenly and continuously. So when feeding materials should not be too much or too less, and the humidity of the materials should meet the requirement of the machine .Incorrect operating method would increase the wearing for the machine, for long times working, it would lead accident.

The main advantage of the hydrometallurgical process is that it allows processing of raw materials, for which the use of conventional methods is not economical or is troublesome [5,6,7]. Hydrometallurgical processes are used for recovery of many metals, including uranium, copper, cobalt, nickel, zinc, aluminium, titanium, gold and lanthanides., the electrochemical refining of metals obtained by pyrometallurgical process, or roasting and high-temperature reduction of hydroxides precipitated from solutions obtained by ore leaching) [1,2,3,4].Hydrometallurgical processes are often coupled to pyrometallurgical ones (e.g. Moreover, they are used in the nuclear industry for the processing of spent nuclear fuel and the recovery of thorium, zirconium and hafnium [9,10,11].
Kimberlite diamond mining is the most profitable type for large-scale mining, and, to date, more than 600 such pipes have been discovered in Angola.Two types of diamond digging are found: industrial open pit mines on the volcanic pipes (known as kimberlite) and alluvial mining, of diamonds that are washed out from the pipes.
After 29 to 36 days the specimens were removed from the solution and the Profile Grinder Kit  was used to take the powdered concrete samples from different depths (up to 8–10 mm) for the determination of the chloride ions. The concrete layers were 1 mm thick. The determination of chloride ions was carried out using the Volhard argentometric method . The effective coefficient of chloride ions diffusion was determined by adjusting the following equation:c=c0[1−erf(x2Defft)].
The estimated d95Au values were established from size-by-assay of the gravity concentrates. For higher grades, the precision values for ROM high- and very-high grades are ±28–31%, which is not unreasonable. The results validate the practical choice of 150 kg samples to support the new sampling and testwork campaign.The pilot study results were used to validate the sampling strategy, providing characterisation data across the domains (Table 23).
