(1). Grinding. It involves reducing the size of tin ore particles. It is usually accomplished through crushing and grinding stages using various types of equipment, such as jaw crushers and ball mills. The purpose is to obtain a suitable particle size range for effective separation during flotation.
According to the different properties of copper oxide ores, there are sulphidizing flotation, fatty acid flotation, amine flotation, emulsion flotation and chelating agent-neutral oil flotation method.
A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more. In the case of this study, it is assumed that a separate lead-copper circuit is not warranted. The flotation section consists of two 10-cell "Sub-A ...
