Ferro Silico-Manganese (FeSiMn)‚ which is one of the Ferro Alloys used in Steel manufacturing. In simple words‚ (FeSiMn) is made by smelting a mixture of mainly Manganese ore‚ quarts‚ energy coal and some additives in big blast electric furnaces. Most of these input raw material is imported from overseas‚ mainly South Africa‚ Australia and the United States. After smelting‚ the cast produced go through a process of crushing and screening to finally have the finished product in a rock form with diameters

Lead is an element that occurs naturally in the environment. Small amounts of lead can be found in the earth’s crust. Most people know it to be harmful to humans but research shows that it does have some beneficial uses. Lead is found in the air‚ soil‚ water‚ and inside our homes. Much of the exposure that we receive comes from our daily activities‚ such as some types of industrial facilities‚ the use of fossil fuels and past use of lead-based paint in homes.

Many metals in nature are in a combined form with sulfur. When smelting or roasting refines these ores‚ the sulfur in the metal combines with oxygen to form sulfur dioxide. The biggest source of sulfur dioxide is from burning fossil fuels in industry and in homes. Coal contains .5 percent to 5 percent sulfur. Sulfur
