In each test, 200 g of mineral (Cp alone or 100 g each of Cp and Py in mixtures) was added to 300 cm 3 of demineralised water and known amount of lime in a Galigher laboratory mill to produce a pulp with a particle size distribution (PSD) of 80% passing 105 μm at pH 10. The mill product was then conditioned in a 1.5 dm 3 flotation cell (Agitair LA-500R) at pH 10.5 with xanthate collector (200 ...
On the other hand, data gathered from experimental test work are adequately described by upgrading lines such as those of the Mayer curve (Mayer, 1950), currently used in mineral processing for assessment of the separation efficiency. It relates the metal recovery with yield, being drawn in the basis of the upgrading balance.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
