Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid.
It's easy to see what phosphate mining can do to an ecosystem. Strip mining removes 20 to 40 feet of the surface of an area to get to the phosphate. In the process, the entire environmental system, including the surface and underground water flows; topography, animals and plants are changed.
The phosphate was mined by pickaxe, at a rate of about 15 acres per year, until the advent of the steam shovel created a mining boom by the 1920s. The town of Nichols was a typical mining town of the period, with a company store and company housing.
Phosphate mining helped to jump-start, and remained an integral part of, the lowcountry fertilizer industry. Ravenel and others established the Wando Fertilizer Company in 1867, while Pratt and Christopher G. Memminger began what became the Etiwan Phosphate Company a year later.
After mining, state-approved reclamation programs will result in productive land uses, including enhanced wildlife habitat and recreational opportunities. How Phosphate is Recovered Phosphate rock is usually found 15-50 feet beneath the ground in a mixture of phosphate pebbles, sand and clay known as phosphate "matrix."
In fact, the Omanis' investment in phosphate in Namibia came after he led a business delegation, including Katti, to the Middle East in 2013 when he was Prime Minister. The fishing sector directly employs over 13 000 people, and around 200 000 if the number is expanded to netmakers as well as the repair and maintenance of vessels and packing ...
Most mining is by open pits and strip mining and the rock requires little processing other the the removal of the non-phosphate bearing rock and other impurities. This process involves crushing and separating impurities (sediment, bones and shells) from the phosphate rock.

After mining, state-approved reclamation programs will result in productive land uses, including enhanced wildlife habitat and recreational opportunities. Sounds good, in theory. But let's take a deeper look at facts of phosphate mining, past catastrophes and why Mosaic's version of "reclamation" is so far off the mark from what could be ...
those phosphate rock processing operations associated with fertilizer manufacture are discussed here. Florida and North Carolina accounted for 94 percent of the domestic phosphate rock mined and 89 percent of the marketable phosphate rock produced during 1989.

Phosphate mining disturbs between 3,000 to 6,000 acres annually in Florida. Approximately 25 to 30 percent of these lands are wetlands or other surface waters. The Mining and Mitigation Program administers reclamation and stormwater management programs for mining operations in Florida, including phosphate.

Idaho's phosphate mining district is the consistent, solid performer in the state, employing 2,000 workers at several companies, including Monsanto and the J.R. Simplot Company. Since the 1970's, mining companies have had to reclaim the land.

And phosphate mining in Florida, which is home to the world's largest phosphate mine, is being challenged by environmentalists concerned about its impact on waterways and drinking water supplies. Already, like other key commodities with once-dominant sources running low, the price of phosphate is starting to yo-yo alarmingly.
