Response Of Ryegrass To Phosphate In The :
m.s. sarir et al. response of ryegrass to phosphate in the reclamation of coal mine soil 204 three rates of phosphorus, representing the addition of 50, and 100 kg ha-1 as sodium dihydrogen phosphate were compared for both crop yield and phosphorus uptake.the word apatite is derived from the greek word for deceit, apate because apatite can be mistaken for many other minerals. It is usually green, but can also be blue, yellow, purple, or brown. apatite is the main source of phosphorous, an important nutrient required by plants. As such, apatite is the key ingredient in phosphate fertilizers.layered oolitic texture as well as high phosphorus content is regarded as one of the most refractory iron ore resources.35) besides, phosphorus is mainly in the form of apatite, where the particle size of the crystal is very fine and not easy to separate. therefore, the

Apatite Its Uses As A Mineral And Gemstone:
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.the main phosphorus minerals in coal are a calcium phosphate and the two crandallite group minerals the average phosphorus content of world coals is estimated by bertine and goldberg mated the average phosphorous content of coal to be 0.05% or 500 ppm on a worldwide basis. although this is close to the average phosphorous content of 420 ppm for sedimentary rocks it is less than 700 ppm for soils there have been a number of studies investigating the distribution
Modes Of Occurrence Of Minerals In The Carboniferous Coals :
aug 25, 2016 phosphorus is not uniformly distributed within the wuda coal seam. the maximum content of apatite in wuda coals in certain horizon can reach up to 91.4 corresponding to the fluorine and concentrations of 2803 gg and 5.96phosphorus concentrations than those from the lower part. In all three coal-bearing formations, the amount data scatter within individual se.ams can be very pro- nounced. the range in average clean coal phosphorus concen- trations, 0.030 to 0.044 per cent, is smaller than the range.mineral of the month club june 2016 ph. 594 email: page apatite stems from the greek apat, meaning deceit and alluding to the difficulty in distinguishing apatite-group minerals from beryl and certain other minerals.
