How phosphate is mined and processed

Mining Sedimentary phosphate tends to be found in loose sediment, so it can be mined with dredge lines (or picks and shovels). In Florida, the phosphate is found mainly in one layer of clay and sand that''s about 10-20 feet thick, and 15-50 feet below the surface. After the heavy equipment digs out the overburden (the sediment above the desired

Coliform Bacteria in Drinking Water Supplies

The most basic test for bacterial contamination of a water supply is the test for total coliform bacteria. Total coliform counts give a general indication of the sanitary condition of a water supply. Total coliforms include bacteria that are found in the soil, in water that has been influenced by surface water, and in human or animal waste.

Introduction to Clay Minerals & Soils

Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earth''s surface. They are found most often in shales, the most common type of sedimentary rock. In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil.

Soil Bacteria | NRCS Soils

Bacteria are especially concentrated in the rhizosphere, the narrow region next to and in the root. There is evidence that plants produce certain types of root exudates to encourage the growth of protective bacteria. Bacteria alter the soil environment to the extent that the soil environment will favor certain plant communities over others.

Clay

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...
