APATITE BACKGROUND INFORMATION. Apatite is the name given to a group of three related minerals the most common of which is fluorapatite(Ca 5 (PO 4) 3 F), and more rarely clorapatite(Ca 5 (PO 4) 3 Cl) and hydroxylapatite(Ca 5 (PO 4) 3 OH). A complete solid solution series exists between these three with F, Cl and OH substituting for each other.

Since apatite is the dominant phosphate-containing mineral in the waste materials, a study was conducted using research-grade apatite, devoid of any ancillary clays and minerals. Using the crystalline apatite in the acid-alcohol leaching tests provided evidence as to why the extractions are incomplete.

A large apatite-iron tailings deposit is located north of Sweden in Kiruna and Malmberget, containing a substantial amount of P 2 O 5 (4–8%) from the previous magnetite recovery. Efforts are being made to ensure the efficient extraction of the minerals of interest with a minimum CO 2 footprint.

The Palai-Islica deposit (Almería, SE Spain) is an Au-Cu epithermal deposit hosted in Neogene calc-alkaline andesites and dacites from the Cabo de Gata-Cartagena volcanic belt in the Betic Cordillera. Major element compositions of apatite from Palai-Islica orebody and related hydrothermally altered and unaltered volcanic rock from the region …

The carbonatite-hosted apatite deposit of Jacupiranga is located in southeastern Brazil. The major styles of apatite mineralization are veins or veinlets, small pods or patches, disseminated apatite, and massive aggregates (locally). The concentration of apatite involves grinding of the carbonatite, removal of magnetite with a magnet drum,

Apatite is not a single mineral but a group of phosphate based minerals that includes hydroxylapatite, fluorapatite and chlorapatite. Fluorapatite is by far the most common variety and can be found as both hexagonal crystals in many colors and massive forms. The stone from Madagascar generally referred to as "Blue Apatite" is a massive form of fluorapatite.

Carbonate mineral flotation is usually carried out using fatty acids as collectors and inorganic acids as apatite depressants, especially sulfuric and phosphoric acids (H 2 SO 4, H 3 PO 4), under slightly acidic conditions (pH 6.0–5.0). A large number of researchers have been trying to achieve high selectivity of depressants to remove carbonates.

The crystalline form of apatite, the natural brittleness of the mineral will contribute to the primary destruction of the mineral during ore grinding and the concentration of apatite in smaller grades.
