Research on Enrichment of P2O5 from Low-Grade

2019-2-3  In the process of phosphorus enrichment, the low-grade phosphate ore is often calcined by a type of thermochemical beneficiation process, or leached by a strong acid such as sulfuric acid, hydrochloric acid, or phosphoric acid. However, the current methods are not very economically efficient and environmentally friendly.

Double reverse flotation of a very low grade

2011-9-14  Phosphate ores in terms of quality and P 2 O 5 grade can be divided into three groups: low grade ores (12–16% P 2 O 5), intermediate-grade ores (17–25% P 2 O 5), and high-grade ores (26–35% P 2 O 5). Deposits consisting of 28–38% P 2 O 5 are considered commercial-grade phosphate deposits and are economic to mine and process (page 135 Sengul et al., 2006).

Double reverse flotation of a very low grade

In this study, reverse flotation was applied to recover phosphate from a very low grade (5.01% of P 2 O 5) sedimentary ore. Sodium silicate, starch, tannic acid, aluminum sulfate, (Na,K)Tartarat, sodium tripolyphosphate, H 3 PO 4, and H 2 SO 4 were used as phosphate mineral depressants in acidic and alkaline conditions. Oleic acid and Armac-T were added as carbonate and silicate collectors
