The process of mining and beneficiation to produce one ton of commercial rock phosphate (32 % P2O5) requires approximately 0.9 GJ/tonne rock or 2.9 GJ/tonne P2O5. If the rock is calcined the total energy requirement is doubled (Ullmann, vol. A 19, 1991). References: BAT N° 4 (1995).

In general, phosphate rock reserves are materials that can be economically produced at the present time using existing technology. Phosphate rock resources include reserves and any other materials of interest that are not reserves. A reserve base is a portion of the resource from which future reserves may be developed.

Acid leaching of phosphate rock was first proposed in 1970s [10, 11], in the hope of avoiding beneficiation losses. In 1990s, some researchers begun to investigate the technique of leaching phosphate rock via organic acids solution [ 12 – 14 ], and since then some researchers have further studied approaches to utilize the low-grade ores [ 15 ...

The phosphate rock slurry which has been so treated in the conditioning vessels is then continuously flowed to the first stage ...

When this technology is used, monocalcium phosphate is obtained. When the solution is evaporated, double salts are obtained: – Nitric acid: Ca(NO 3) 2.Ca(H 2 PO 4) 2.2H 2 O [or CaNO 3.H 2 PO 4.H 2 O], known as calcium nitrate phosphate; – Hydrochloric acid: CaCl 2.Ca(H 2 PO 4) 2.2H 2 O [or CaCl 2.H 2 PO 4.H 2 O], known as calcium chloride phosphate.. These can …

Consumes low-quality rock with high silica and other impurities. P2O5 as low as 10-15% vs ~30% for wet-acid process.

The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of …

Mining & Beneficiation. The configuration of a phosphate mine and beneficiation plant with the related facilities is important economically, because phosphate rock has a relatively low unit value. KEMWorks specializes in integrating geology, mining, and beneficiation with the downstream facilities that process phosphate rock.
