The addition of lime at the cooking and steeping stages helps to remove the seed-coats. The by-products are either thrown away or fed to pigs. Originally, the maize was converted into dough by grinding it a number of times with a flat stone until the coarse particles were fine enough.
It is extensively used in various industrial and chemical applications. The hydrated lime powder manufactured by us is considered to be the best chemical reagent and so it is widely used in various specialty chemical applications. Here we take a look at the main production process of hydrated lime. The heart of a lime plant is the kiln.
Lime is used extensively in the recovery of gold and silver. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution, keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.

Slaked lime can be blended into lime slurry, lime putty, lime mortar etc. Which can be used as coating material, brick & tile adhesive. Limestone is the main raw material of glass production. Calcium carbonate can be directly processed into aggregated rock and burnt into unslaked lime. There are two types of lime: unslaked lime and slaked lime.
