All About Garnets
The six best known garnet minerals are almandite, grossular, pyrope, spessartite, andradite and uvarovite. These minerals are only the pure end members of the garnet family, and most garnets found in the field are more complex and certainly not pure. Almost all garnets are mixtures, mostly of the six end members mentioned above.

Mineral Processing Method To Remove Impurities In Feldspar
Iron removal by flotation can be perfect for iron-containing minerals in clay and fine-grained grades, but it is ineffective for hard ores. For severely weathered ores, secondary sludge may be produced in the stage of crushing and grinding, which is likely to cause high viscosity of flotation foam, resulting in lower collector selectivity and poor effect.

Lead and Zinc
Treatment of lead and zinc ores begins with milling. Milling is a multi-stage crushing and grinding operation. It involves coarse crushing followed by wet grinding. Crushing is usually a dry operation that utilizes water sprays to control dust. Primary crushing is often performed at the mine site, followed by additional crushing at the mill.

MINERAL ABRASIVES IN SOUTH AFRICA-2
Garnet is a brittle, transparent to subtransparent mineral, which has a vitreous lustre without cleavage and may have various colours, the most common being red (Hardness 7). Angular fracture and high resistance to chemical and physical attack are qualities that determine garnet as a suitable material to be used in abrasives.
