Dewatering. Dewatering and solid–liquid separation is an important part of any mineral processing plant. It spans a range of stages, from feed preparation to concentrate handling and tailings disposal. Our experience in this area is extensive, and includes thickener and filter technologies from testing to specification and control.
quantity of mineral ore (called the 'strip ratio') is usually greater than one, and can be much higher. For example, if a proposed mining project involves the extraction of 100 million metric tons of mineral ore, then the proposed mining project could generate more than one billion metric tons of .
