ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

Continue this process until all ingredients have been added. This will ensure that the ingredients were exposed to the lowest possible temperature and thus enhance the stability of the final product. The cooling step in an ointment's preparation is an important part of the compounding process.

Additives may be added to diesel fuel at three different stages: (1) at the refinery, (2) in the fuel distribution system, and (3) after the fuel has left the control of the producer. Additives of the latter group, when added by the end user or a reseller, are called aftermarket additives.

Impeller is needed for mixing ingredients and chopper for further granulation. All dry ingredients are agitated into the mixing bowl and then run the chopper blade in order to achieve granulation. The binding agent is added during the blending process through a spraying nozzle. Fluidized bed granulator.

In BOS, recycled scrap steel is added into the molten iron. At a really high temperature, oxygen is blown into this mixture to reduce the overall carbon content. In EAF, however, the recycled steel scrap is put through high-power electric arcs (of temperatures as high as 1650 C ) in order to fully melt it and convert it to high quality steel.

EAFs are mainly used to produce special quality steels which are alloyed with other metals. EAFs can also be used to produce ordinary, non-alloyed steels. Unlike the furnaces, EAF's do not use hot metal. They use scrap steel from recycled products. The scrap steel is tipped into the EAF from an overhead crane.
