The effects of blasting on crushing and grinding are poorly understood. Comminution may take advantage of internal cracking and weakness in the rock caused by an explosive shock from blasting. However, quantifying this phenomenon will require a multidisciplinary investigation involving the physics of rock breakage, mining and mineral processing ...
Gravity separation is the traditional method for mineral beneficiation and irreplaceable when process minerals such as tungsten, gold, iron, tin, chrome, tantalum, niobium, coal, barite, etc. Because of its advantages such as low running cost, environmental protection and special effects on some minerals, it is still very popular at present.
