Treatment of phosphate rocks with hydrochloric acid

2010-7-17  The use of hydrochloric acid, did not receive much attention [8–11]. Solutions containing mono-calcium phosphate obtained by leaching phosphate rock using diluted hydrochloric acid were treated for uranium and lanthanides recovery prior to P 2 O 5 recovery. The separation of lanthanides with similar chemical properties is a challenging task.
