WATER TREATMENT
1
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.
ANIMAL FEED
2
Limestone is an economical calcium source and vital ingredient in mineral feed supplements, which fortify organic feeds for farm animals and poultry. Calcium carbonates high levels of elemental calcium. Limestone grit in poultry gizzards assists with digestion and also provide calcium fortification to strengthen the egg shell.
Dolomite should not be used in chicken feed as excess magnesium might reduce egg output.
INDUSTRY
3
Limestone applied to pyro-metallurgical processes is called fluxstone. The use of limestone over lime 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.
GLASS
4
The manufacture of glass is an excellent example of the complementary, interchangeable use of limestone and lime. Limestone is significantly cheaper than lime and a lot easier to handle and store.
The Fe content of the limestone is critical and must be manage with the Fe content of other raw material in the glass making process.
AGRICULTURE
5
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.
