Issues The Phosphate Risk
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. Large amounts of water are retained during the mining process.
Chemical Processing of Phosphate
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.
ASSESSING THE DESIRABILITY OF MARINE PHOSPHATE …
• The marine mining of phosphate mineral resources is unwarranted in South Africa since it would intensify phosphate flows and in the process cause a rise in the phosphate quantity entering the environment. • There exists more socioeconomically and environmentally friendly approaches to sustainably obtaining supplementary phosphates. These
