Limestone is an economical calcium source and a vital ingredient in mineral feed supplements, which fortify organic fees for farm animals and poultry. Limestone grit in poultry gizzards assists with digestion and also provide calcium fortification to strengthen the egg shell. A vast tonnage of limestone enters the agriculture fields as direct application to soil and as a filler for mixed fertilizer. Liming neutralize soil acidity, is a direct source of nutrients, increase organic matter, increase soil micro-organisms and most importantly increase the efficiency of fertilizers. By changing physical and biological properties of soil Lime increases microbial activity and increases fertilizer effectiveness. Limestone is by far the lowest-cost acid neutralizer per unit of basicity and the most widely available. When complete or over-neutralization is required a limestone-lime treatment process can be employed. Limestone is ideal for use in passive systems to treat acid mine drainage (AMD) due to the low cost of the raw material. The manufacture of glass is an excellent example of the complementary, interchangeable use of limestone and lime. Limestone is significantly cheaper then lime and a lot easier to handle and store. The Fe (iron) content of the limestone is critical and must be managed with the Fe content of other raw material in the glass making process. Limestone applied to pyro-metallurgical processes is called fluxstone. The use of limestone over time depends on the smelting process and the cost of calcining the limestone as part of the process. A number of smelters use lime during the dry winter months when electricity is expensive and change over to limestone during the wet summer season. Limestone is easier to handle during the rainy season and the raw material cost benefit outweighs the extra electricity cost.
