Overview of South Africa's Phosphate Fertiliser Industry

phosphate in the form of apatite are exploited in South Africa, Brazil, Russia, Finland and Zimbabwe. The agricultural sector for the production of fertilisers is the principal consumer of phosphate rock, accounting for 80-85 percent of total production. The South African fertiliser industry is currently in a mature stage.

Phosphate in South Africa Journals

From 1930 to 1934 a small company named South African Phosphates Ltd mined high-grade apatite pockets in the pyroxenite, ground the mineral, bagged it, and sold it as fertilizer. Apart from being insoluble to plants, the apatite was more expensive than imported Moroccan phosphate rock, and the operation soon went bankrupt.

Jan 28, 2015 Mining first began in the United States in 1867 in South Carolina. Phosphate rock was discovered in central Florida in the 1880s, and because of the extensive, high-quality deposits and lower mining cost, it quickly became the leading phosphate-producing state. Currently, phosphate rock is mined in Florida, Idaho, North Carolina and Utah.

Apr 30, 2019 Today, rock phosphate is the only raw material in the form of P fertilizers. There are two types of rock phosphates: igneous and sedimentary; both have the same phosphate mineral, i.e., calcium phosphate of apatite group.

Gemstone Information Apatite Meaning and Properties

Apatite is found in Myanmar (Burma), Brazil, India, Kenya, Madagascar, Norway, Sri Lanka, South Africa, Mexico, Canada and the United States. There are three minerals that actually contribute to apatite, which is the reason for the varied colors and shades of this stone. Apatite is calcium phosphate combined with fluorine, chlorine or hydroxyl.
