Water in Mining & Processing Phosphate Ore

A large low-cost supply of water is an important factor in the economical production of large tonnages of phosphate concentrates. The highest grade Florida phosphate concentrate sells for about nine dollars per long ton f.o.b. plant. Yet in terms of plant growth and food no mineral is more important to mankind. Conservation and Reclamation of Water The phosphate industry has long been aware .

to increase the grade of mining product (concentrate). Phosphate ores can be beneficiated using one or a combination of different methods.19‒21 The most common ones are: flotation crushing des-prm separation grinding and washing (Figure 1).

Environmental impact of phosphate mining and beneficiation .

Phosphorus is common within geological materials. The average continental crust contains 0.27% P 2 O 5. 1 Phosphorus is the primary resources to produce fertilizer and phosphorous-based products. 2 Phosphorus is neither substitutable nor recyclable therefore the total demand must be provided through the mining beneficiation and chemical processing of phosphate ores.

The bulk of the phosphate we mine – about 90% – is used to produce phosphate fertilizers. Another 5% is used to make animal feed supplements. The remaining 5% goes into making a variety of products from soft drinks to toothpaste to metal coatings. Phosphate is a limited resource that cannot be replaced.

During surface mining overburden is drilled blasted and removed by dragline to the side of the mining area for subsequent reclamation. Small draglines electric shovels and bulldozers recover the upper ore body. The intercalating limestone layer is then blasted and removed to expose the phosphate bed which is loaded onto trucks.

Processed phosphates — little-discussed but widely spread throughout the food chain — pose a serious threat to our environment. Phosphate rock mining along with the inorganic fertilizers and animal feed supplements for which phosphate is mined pollute our air contaminate our water and destroy invaluable wildlife habitat.

Phosphate mining in the United States - Wikipedia

The phosphate mining industry employed 2200 people. The value of phosphate rock mined was US$2.2 billion. As of 2015 there are 10 active phosphate mines in four states: Florida North Carolina Idaho and Utah. The eastern phosphate deposits are mined from open pits.

What Is Involved in Phosphate Mining? (with pictures)

Many different chemical processes use phosphates and phosphate mining is one of the most important sources of phosphorous for use in the synthesis of chemical fertilizers. Phosphate deposits are inorganic but are often laid down as a result of biological activity in the distant past.

Phosphate Mines | Earth Resources Observation and Science .

Modern phosphate mining involves complete removal of the land—plants animals soil water even bedrock—and then its approximate reconstruction minus the phosphate. The steps are as follows: The area to be mined is first stripped of vegetation and the water table is lowered typically by digging a deep trench around the area.

Locations of Deposits

Almost all phosphorus is mined as phosphate rock (PO4). Deposits are typically found in shales cherts limestone dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks. One of the world's largest phosphate deposit is the Phosphoria Formation located in southeast Idaho.
