The final product of this stage is phosphate rock. The subsequent phosphate processing operations also require sulphur, sulphuric acid and ammonia.What Is Involved in Phosphate Mining? (with pictures),Phosphate mining involves the extraction of ores containing chemical compounds rich in substances that contain the phosphate ion. These ores vary in their composition, and different varieties of phosphate rock require different mining techniques. Processing of the mined ore follows extraction. Finally, mining sites are rehabilitated to minimize long-term damage to the environment from the,

10/02/2016· To this end, the test and selection of the specific chemical reagent for efficient chromium extraction from phosphate ore were studied. The effects of some parameters were taken into consideration and optimized. The results show that the chromium content was reduced to approximately 30% in natural phosphate using citric acid as extracting solution.

Swapan Kumar Haldar, in Mineral Exploration (Second Edition), 2018. 13.5.7.5 Flotation of Rock Phosphate Ore. Rock phosphate, the primary raw material for fertilizer and phosphoric acid, occurs as high-grade ore (+30% P 2 O 5), medium-grade ore (20%–30% P 2 O 5), and low-grade ore (15%–20% P 2 O 5). The very high-grade ore blends with medium-grade ore for directBeneficiation of Low-Grade Phosphate Deposits by a,,grade of 9%–10% (low-grade). Various pre-processing and processing methods have been developed for concentrating low-grade phosphate up to marketable grade and this study aims to select the optimal method to produce an economically viable grade of phosphate concentrate from low-grade ore. Different concentration methods, including calcination and gravity separation, were applied on samples,
