| Abstract: | The new method is introduced for recovery of magnesium from lowgrade phosphate rock with high magnesium content by adopting selective chemical reaction.In the process,the loss of phosphorus is about 2% while the w(Mg(OH)2)of the recovered product as flame retardant is over 95%.This technology not only solves the problem of separation magnesium from phosphate rock,but also brings the economic benefit. |
