P a g e 2 concentrate. The comminution circuit includes both crushing and milling processes and the magnetic separation circuit consists of two different types of magnetic separation plants. No chemical reagents are required for this process other than a non toxic flocculent product.
overseas, including magnetic separation and flotation, which allow ores with as little as 20% talc to be mined. However, it is also common for other associated minerals, such as tremolite, magnesite and dolomite, and even sulphide concentrates, to be extracted from the same ore for commercial use. Some of the associated
overnight at 90oC. Highly magnetic minerals are removed using a hand magnet, followed by one or more passes through a rotating rare earth element magnetic separator, also designed at the Carlisle laboratory. The remaining material is processed using a Frantz isodynamic magnetic separator. For the first pass, a longitudinal tilt of 20o, a

small individual heavy mineral grains. Once the rock is reduced to grains, it is necessary to separate the grains into paramagnetic and nonparamagnetic and heavy and light mineral fractions. In separating grains by property, those minerals chemically suited for radiometric dating are abundantly concentrated. Grams of mineralogical
To obtain minerals suitable for age dating and other analyses, it is necessary to first reduce the mineral bearing rock to a fine, sand like consistency. Reducing whole rock requires crushing, grinding, and sieving. Ideally, the reduced material should range in size from 80 to 270 mesh . The openings in an 80 mesh sieve are equal to 0.007 inches, 0.177 ...
