These raw materials are proportionally mixed at different stages of the production process inorder to produce an intermediate product called clinker and final product of cement. The technology of cement production involves several unit operations, and are complex to enumerate. However, the major unit operations are the following:-


A reasonable standard is the designed, or established, daily clinker production assuming 85% annual run factor and 5% cement additives: Annual cement capacity = Clinker tlday x 365 x 0.85 / 0.95 Some elaboration is still required for the plant which produces 3,000t/day of clinker and 6,000t/day of cement, but it is better under- stood as a 980 ...

Aluminum facts - NRCan

Production. Aluminum does not exist in a pure state in nature. The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide. It takes approximately 4 to 5 tonnes of bauxite ore to produce 2 tonnes of alumina.
