Coke making. The main solid wastes generated in the production of metallurgical coke are coal dust, coke dust, tar sludge and acid sludge. Coal dust is recycled back through the coal blend. Coal dust can also be recycled along with coke dust by adding them in the sinter charge mix. Tar sludge is added to the coal blend to improve its density.

Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.

Mechanical size reduction of solids inevitably results in wear of the grinding tools, the socalled abrasion. This means that during grinding, for example with grinding tools made of steel, a certain amount of steel components as well as heavy metals, chromium, etc., can be introduced into the sample. Generally, abrasion is in the ppm or ppb range.
