Levels of exposure were estimated for the following operations: milling, mixing, machine line, sawing, and grinding. Asbestos concentrations ranged from 1.5–6.3 f/mL in 1956, to 0.3–5.0 f/mL in 1969, and to 0.9–1.7 f/mL in 1975. In all three time periods, the highest concentrations were observed in the milling and grinding operations.

Washing and Screening Phosphate Rock At the washer the water-matrix slurry discharges into a surge receiving bin or tub and is screened for removal of clay, sand and fine phosphate from the mud balls. The screen oversize passes through a hammer mill to break down the mud balls and occasional large pebbles.
Phosphate esters possess outstanding load carrying and corrosion inhibition properties which makes them ideal for oil and transport applications. Phosphate esters are often used as amine/amido – amine salts to enhance their corrosion inhibition properties. PEX™ 136(m) in its amine neutralised form is recommended for oil field applications.
Leaders Against Waste. Currently, about nine times more phosphorus is extracted from the ground each year than we actually consume, much of this lost to waste. And the production of phosphoric acid generates about 35 kg of hazardous phospho-gypsum per person each year. The phosphate industry can do better, and we are here to lead the way.
The total water use in the South West Florida Water Management District (SWFWMD) in 2011 was 1,022 MGD. Of that, approximately 2 percent was used for mining operations. This includes water use for phosphate, peat, limestone, sand, shell and gravel mines. Mosaic's share of the mining and dewatering category is less than 2 percent of the total ...
Crushing is the first stage in phosphate beneficiation process Primary size reduction generally is accomplished by crushers and grinding mills Some classification of the primary crushed stone may be necessary before secondary grinding takes place Extensive crushing and grinding is necessary to liberate phosphate from the material.

The source of fluorides is phosphate rock, which contains from 3.5% to 4.0% (w/w) fluorine. The fluorine is generally precipitated out with gypsum, leached out with phosphoric acid product, or vaporized in the reactor or evaporator. The reactor where phosphate rock is contacted with sulfuric acid is the primary source of emissions.
The major airborne emissions occur in the form of fine rock dust from drying and grinding operations of phosphate rock. Collective dose commitments resulting from atmospheric releases of 238 U and 226 Ra from phosphate rock processing plants were estimated for the case of inhalation during the passage of radioactive cloud, ( Table 6 ).
