Method For Etching Phosphate Ores

the inventive method for etching phosphate ores involves a single-pass digesting of ores whose p 2 o 5 content is greater than 20% in weight by at least 10% in weight of a hydrochloric aqueous acid solution associated with an etching solution formation and the separation of the insoluble solid phase and the aqueous phase of said etching solution..method for etching phosphate ores,a method for etching phosphate ores includes a single-pass digesting of ores which p 2 0 5 content is greater than 20% in weight by a hydrochloric aqueous acid solution having an hci concentration less than 10% by weight with an etching solution formation and the separation of the insoluble solid phase and the aqueous phase of the etching solution..contributions to general geology 1955,commercial name for zirconium oxide ore. 1 alvite, cyrtolite, hagatalite, malacon, naegite, oyamalite, and yamagutilite are names given to varieties of zircon. some of the names are not well denned, but in general they apply to varieties of zircon that contain appreciable water and may contain rare earths, uranium, tnorium, beryllium, and p205.

ratios of co2/p205, f/p205 and cao/p205 indicate a carbonate-hydroxyl- fluorapatite species (francolite) with its composition as cas(po4)3 (f, ci, oh, co3). the co2/p205 ratio varies from 062 to 077 indicating a possible substitution of co~ 2 for po,~ 3..12arocks: metallurgy important questions,such diagrams helps in predicting the feasibility of a thermal reduction of an ore. ∆g must be negative at a given temperature for a reaction to be feasible. · 2x m(s) + o 2 (g) → 2m x o(s) in this reaction ∆s=-ve because solid and gaseous reactants are changing to metal oxide which is solid, hence entropy decreases. ∆g will be +ve if.fertilizers: definitions and calculations,in weight percentage of n, p205, and k20 in the order n-p-k the grade is only the amount of nutrient found by prescribed analytical procedures, excluding any nutrient that is unavailable to plants. for example, a grade of '10-15-18' indicates a fertilizer containing 10 % n, 15 % p205, and 18 % k20.

Mineralogical Aspects Of Beneficiation Of Phosphates

in the same way as for p20~ and c02, we can obtain the following expression that relates the concentrations of p205 and so3 in francolite: p205% =7.04(6-0.125 so3% ) (5) ap2 o5 % = - 0.88 so3 % (6) now the p205 concentration in the phosphate ore may be expressed as: p205% = (42.3-1.6 c02%-0.88% so3% )(1- =~id~) (7) where 42.3 is the weight.continuous beneficiation of dolomitic phosphate ores,ore bodies. the amount of coarse parti­ cles suitable for phosphate pebble is al­ so drastically reduced. the p205 content is lower, and the amount of mgo increases owing to the presence of carbonate min­ erals (4). at pl.'esent high-mgo ores are bypassed during mining operations because.thianthrene, phenothiazine, and 9,10-diphenylanthracene,model 564 storage oscilloscope (tektronix, inc., beaverton, ore.). results and discussion background. a typical cyclic voltammogram of the back- ground current in liquid so2-0.15 m tbap at -40 'c at a platinum disk electrode is shown in figure 1. the useful po- tential range observed here is about -
