florida hard rock. the florida hard rock district mines phosphate from a belt up to 30 miles (48 km) wide and 150 miles (240 km) long, extending from tallahassee on the west to pasco county on the east. phosphate deposits occur in bradford county, hamilton, and union counties.
what is apatite? apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. they are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals. apatite has a relatively consistent hardness and serves as the index mineral for a hardness of five in the mohs hardness scale.
phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. the phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (p 2 o 5). marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than
phosphate sory mineral in the 3 rock classes. hardness of phosphate rock for grinding impact crusher especially suitable for hard rock crushing and make it read … learn more. the phosphorous content in these rocks is mainly derived from the presence of apatite minerals.
the organic phosphate is the phosphate that is bound or tied up in plant tissue waste solids or other organic material. after decomposition this phosphate can be converted to orthophosphate. phosphate rock in commercially available form is called apatite and the phosphate is also present in fossilized bone or droppings called guano.
Environmental Protection and Health One
LUM is of little dust and noise, achieving Environmental Protection Request, it is quite environmentally friendly
To Improve the Purity Two
Low investment cost: LUM use PLC/DCS automatic control system, well save the cost of operators.
High Efficiency Three
LUM has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.
Low Cost Four
Utilize advanced working principle and reduce the grinding time, as a result, the final products has little iron and the whiteness and purity are raised.
