The use of phosphate rock in energy storage

What is phosphate rock used for?

Phosphate rock (PR) has been used in various applications, such as synthetic construction aggregate in the production of gypsum board, and for highway pavement, foundation, and embankment materials. However, its low utilization rate is due to lack of usability criteria and guidelines.

Can primary data improve phosphorus management in phosphate rock mining?

To improve the sustainable management of phosphorus, numerous LCA studies, using primary data, have been conducted for phosphorus recovery technologies from wastewater, but not for phosphate rock mining. This article addresses this issue by conducting a cradle to gate assessment of beneficiated phosphate rock production using primary data.

Are phosphate bags a good energy storage material?

By referring to the anterior studies, it has been observed that increasing phosphate bags significantly enhances the productivity of solar still, increasing efficiency and productivity. Therefore, phosphate bags are excellent energy storage materials. The use of phosphate-filled cotton bags in the solar still was experimentally evaluated on 3 days.

What is the main use of phosphorus mined from phosphate rocks?

Phosphorus is mined from phosphate rocks for production of chemical fertilizers. In nature, phosphorus is available in the mineral deposits in the form of phosphate rocks. The relative abundance of phosphate rocks in the earth's crust is limited and unequally distributed.

How much electricity does phosphate mining use?

The mining operations require an average of 0.174 MJ final energy per kg of crude phosphate rock (0.725 MJ per kg P 2 O 5) as diesel burned in the machinery. The electricity used during the mining operations is marginal (5.95E-04 MJ per kg of crude phosphate rock and 2.5E-03 MJ per kg P 2 O 5 ).

What is the main product of phosphate rock processing?

The phosphate rock processing industry ranks fifth in the mining industry in the United States. In making fertilizer, phosphoric acid is produced from phosphate. As discussed in Chapter 4, PG is a by-product from processing phosphate rock to produce fertilizers and other chemicals.
