The effects of phosphate mining in Nauru have had significant negative impacts on the island's environment and economy. [1] One of the most prominent effects of the phosphate mining in Nauru is the extensive environmental degradation that has occurred as a result of the extraction of phosphates. [ 2 ]
The economic history of the Nauruan phosphate industry. In the first year of mining alone, 11,000 pounds (5,000 kg ) of phosphate were shipped to Australia. [ 1 ] After World War I the interests of the Pacific Phosphate Company were acquired and the phosphate mining on Nauru was managed through a trust established between Britain , Australia ...
US production of phosphate rock peaked in 1980 at 54.4 million metric tons. The United States was the world's largest producer of phosphate rock from at least 1900, up until 2006, when US production was exceeded by that of China. In 2015, the US produced 12 percent of the world's phosphate rock.
Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion , sinkholes , loss of biodiversity , or the contamination of soil , groundwater , and surface water by chemicals emitted from mining processes.
Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy. The production of fertilizer is the largest source responsible for minerals mined for their phosphate content.
Phosphogypsum is a by-product from the production of phosphoric acid by treating phosphate ore with sulfuric acid according to the following reaction: . Ca 5 (PO 4) 3 X + 5 H 2 SO 4 + 10 H 2 O → 3 H 3 PO 4 + 5 (CaSO 4 · 2 H 2 O) + HX
The mining industry of Morocco is important to the national economy. Morocco is the world's largest producer of phosphate , and contains about 75% of the world's estimated reserves. [ 1 ] Mining contributed up to 35% of exports and 5% of GDP in 2011. [ 2 ]
Phosphate rock production greatly increased after World War II, and remains the primary global source of phosphorus and phosphorus chemicals today. Phosphate rock remains a feedstock in the fertiliser industry, where it is treated with sulfuric acid to produce various "superphosphate" fertiliser products.
