The main product of the smelting process is a carbon-saturated ferroalloy consisting of 76 to 80% manganese, 12 to 15% of iron, 7.5% of carbon, and 1.2% of silicon. 70 to 80% of the manganese is recovered in the melt, and a slag consisting of 30 to 42% manganese is also achieved.

used as cement extenders and major work has been done in improving these cement extender properties3-5. The objective of the pilot plant test work was to develop a process to produce a cement extender from high carbon ferromanganese slags. The slags contained an undesirably high amount of MnO with potential adverse effects on the cement properties.

It is of great importance to innocuity, minimization and reutilization of manganese slag generated in manganese product by electric furnace process. In the paper, ordinary Portland cement was replaced partly by manganese slag to then evaluate manganese slag’ effect on mechanical performances of them.

The concrete industry therefore is enormous, and this comes at a cost: It is estimated that around 7% of the world’s carbon dioxide emissions come from the manufacture and use of cement, the main component of concrete. And a large proportion of this 7% is due to the necessary use of calcium, which is usually obtained by burning limestone.

Cement manufacture accounts for two-thirds of total energy use in the production of non-metallic minerals. In terms of CO2 emissions, cement production is by far the most important activity in this category. Global cement production grew from 594 Mt in 1970 to 2,284 Mt in 2005, and is approximately 2,500 Mt today.

Its inclusion in the process does not behave the same way in all cement kiln systems, so lab and industrial tests are always needed prior to industrial use. Due to the nature of cement process almost any quality of fluorspar or its sub-products(i.e. HF industry residues) can be used for cement production (as low as 40% of CaF2 content) 20

White Cement: The cement when made free from colouring oxides of iron, manganese and chlorium results into white cement. In the manufacture of this cement, the oil fuel is used instead of coal for burning. White cement is used for the floor finishes, plastering, ornamental works etc. In swimming pools white cement is used to replace glazed tiles.
