key of flotation separation of these two minerals is the addition of pyrite depressants (Leppinen, 1990; Fuerstenau et al., 1985). At present, the most widely used flotation separation process involves the addition of a lot of lime in the pulp to inhibit sulfur and float

The earliest tires were bands of leather, then iron (later steel) placed on wooden wheels used on carts and wagons.A skilled worker, known as a wheelwright, would cause the tire to expand by heating it in a forge fire, place it over the wheel and quench it, causing the metal to contract back to its original size so that it fit tightly on the wheel.
