Mineral Processing

Mineral processing techniques depend a great deal on the particle behavior, which in turn varies with its size. Therefore size analysis is of great significance to determine the quality of grind and establish the degree of liberation of valuable minerals between them, as

Mineral processing

Multi-G processes allow the separation of very fine particles to occur (in the range of 5 to 50 micron) by increasing the driving force of separation in order to increase the rate at which particles separate. In general, single G process are only capable of processing particles that are greater than approximately 80 micron in diameter.

3 Ways to Assay Gold

28-3-2019To assay gold using fire, start by placing the gold into a heat-resistant crucible. Then, add lead oxide, sodium bicarbonate, potassium carbonate, and flour to create a flux, and heat everything to between 1,100 and 1,200 degrees Celsius. Next, pour off the top layer of molten glass, and pour the metal underneath into a mold to cool.

DETERMINATION OF MOISTURE AND TOTAL SOLIDS

High moisture samples. Food samples that have high moisture contents are usually dried in two stages to prevent spattering of the sample, and accumulation of moisture in the oven. Spattering is the process whereby some of the water jumps out of the food sample during drying, carrying other food constituents with it.

Although STS also has the ability to bind free calcium, it is not a strong calcium chelator.
