Mineral dryers need to be designed for heavy duty processing. Sanding and eroding – such is the reality of the drying processes of coarse-grained minerals, like sand, and gravel. Also, mineral drying is a critical step in total production process. When drying large volumes of material, energy consumption is the greatest controllable expense.
In the second stage of mineral processing, the valuable mineral or minerals are subjected to size separation, which is the division of particles according to their size. This process is essential for further appropriate concentration process, and it can be carried out dry or wet. Separation processes include screening and classification.
Industrial drying is a process used to reduce the moisture content of materials. Reducing moisture is a vital step in many industrial processes, from food and pharmaceuticals to woodworking and construction. ...

Calcining - also known as calcination - is a thermal treatment process that uses extremely high temperatures to change the physical and chemical properties of various solid materials, including minerals, metals, and ore. Calcining is used in a variety of industrial applications within the mineral processing, recycling, and manufacturing industries.
The benefit to mineral processors is firstly, a step change increase in the grade and recovery of valuable minerals for metals production. Secondly, substantial capex and opex savings flowing from the substantially reduced footprint that a XtractOre™ separation process plant requires, relative to conventional separation processes.
