Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight.

Material Yield Variance shall be calculated as follows: Step 1: Calculate the Standard Yield for the total materials input. Standard Yield = 500 tons x 1000 / 51 KG = 9,804 bags. 500 tons of materials should have yielded 9,804 bags. Step 2: Calculate the Standard Cost of materials per bag. Total material cost of 1 bag of cement: Limestone. 11 KG.

Agricultural lime helps lower the soil’s acidity levels by rendering it more pH neutral. By applying lime to the soil when it becomes too acidic, farmers can ensure they are helping improve their crop output. If crops can’t properly grow, they can’t produce, which impacts the agriculture business and its bottom line.
