copper ore has significant talc throughout most of the ore zones. The levels of talc in some ore zones are high (1-2% would be considered low). Talc is a clay mineral composed of hydrated magnesium silicate with the chemical formula Mg 3 (SiO 3) 4. It occurs as foliated to fibrous masses, and in an exceptionally rare crystal form. It has a

Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
Ball Mills are slow speed horizontal mills with a rugged design and ease of maintenance coupled with excellent performance. Available in sizes up to 15ft / 4.6m diameter and 24ft / 7.3m length.

In this study, we investigate the effect of the ball size in a high-energy ball mill on the comminution rate and particle size reduction. High-energy ball milling at 2000 rpm produces ultrafine talc particles with a surface area of 419.1 m 2 /g and an estimated spherical diameter of 5.1 nm. Increasing the ball size from 0.1 mm to 2 mm increases ...
Talc is a naturally hydrophobic mineral, and therefore it is easily floatable. There have been many studies to overcome this problem, and depress talc with various reagents. In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase.
