Therefore, it is ideal to reject these minerals at an early stage in the process. Sensor-based ore sorters can be effective in the rejection of iron -silicate minerals . These sorters are usually installed after the crushing plant, just upstream of the beneficiation plant. Liberation is a critical factor, as the effectiveness of ore sorting is ...
Grinding is the last stage of the size reduction process after crushing. Grinding is carried out to free the different minerals contained in the ore, to provide the appropriate size and surface area for the enrichment process or the intended use. The grinding process can be dry or wet depending on the enrichment process, different grinders are ...
dynamics. Major process operations are largely related to particulate technology and consist of size reduction (or comminution) by crushing and grinding for the liberation of minerals, separation of mineral particles by va rious principles and a number of operations associated with them.
