May 24, 2016 For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 30-32% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which super-phosphates are produced. The fertilizer market is very competitive.

Phosphate rock does not have a definite chemical composition. The major phosphorus minerals of most phosphate rock are in the apatite group and can be represented by the formula Ca 5 (PO 4) 3 (F, Cl, OH). Phosphate rock occurs as nodular phosphates, residual weathered phosphatic limestones, and consolidated and unconsolidated phosphatic sediments.
Nov 01, 2014 A total of 15 composite surface rock phosphate samples were collected from Uro phosphate deposits. Chisel and hammer were used to break off the phosphate chips, which were then collected in cloth bags. Samples were crushed in a jaw crusher and then ground to very fine powder. 3.2. Methods3.2.1. Digestion of phosphate ore samples
A composite skarn phosphate rock sample was collected from cores of drill holes MS164 and MS211 that intercepted mine Unit 3D containing skarn phosphate mineralization.

Much of the resource extraction conducted in areas of karst is for the rock itself. Unweathered carbonate rocks pro-vide crushed stone and dimension stone
The mined rock is transported to the processing site and stockpiled. The material then is crushed. Depending on the degree of cementation, several stages of crushing may be required to achieve the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing.
