- heavy media separation zinc ore processing
The primary processes are crushing and grinding of ore, ore sizing and separation. To separate the ore into applicable sizes for further processing, screening, classifying, concentration separation, heavy medium separation, gravity and/or magnetic separation, and flotation applications are used.

Sink-Float Tests are classed as bulk or selective separations. A bulk test gives two products, first, the lighter minerals with a gravity less than 2.8 to 3.3 and, second, minerals having a gravity heavier than 2.8 to 3.3. The separation depends on the gravity of the media used. The heavy media generally used are as follows:

In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.

6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
