Serum calcium levels are tightly controlled within a narrow range, usually 8.5–10.5 mg/dL (2.1–2.6 mmol/L). However, the serum calcium level is a poor reflection of overall total body calcium, as serum levels are only 0.1–0.2% of extracellular calcium, which in turn is only 1% of total body calcium.

Phosphate is an abundant mineral found in the body. The body store of phosphate is 500 to 800 g, with 85% of the total body phosphate present in crystals of hydroxyapatite in the bone — about 10% found in muscles and bones in association with proteins, carbohydrates, and lipids. The rest gets distributed in various compounds in the extracellular fluid (ECF) and intracellular fluid (ICF).

depend on the method of production. 2. DESCRIPTION OF PRODUCTION PROCESSES 2.1 Raw Materials for Phosphoric Acid Production Bones used to be the principal natural source of phosphorus but phosphoric acid today is produced from phosphatic ores mined in various parts of the world. Phosphate ores are of two major geological origins:-

Two different production processes can be used in the manufacture of phosphoric acid: • The wet process, which is the most commonly used in fertilizer plants, where phosphate rocks are digested with an acid (e.g. sulf uric, nitric or hydrochloric acid). The tri …
