2.3.4. Synthesis of gypsum. After the recovery of Fe-species, the treated water was rich in sulphate, which was recovered by adding 5 g of lime per L of treated water, thus leading to the formation of calcium sulphate (gypsum) (Liu et al., 2016).The product slurry was recovered as described in Section 2.2.1 and then dried at 105 °C for …
The path to gypsum is four steps long.

Many beneficiation techniques can be employed to upgrade the P2O5 grade of phosphate ores based on their characteristics in chemical composition and texture. The flotation process is most widely applied to balance the P2O5 recovery ratio and cost. In this review, the dominant techniques for the beneficiation of phosphate ores are …
Stage 4: Dehydration. High-efficiency thickener is used to process the phosphate powders, and they are dehydrated by a vacuum filter. The phosphate concentrates are sent to the concentrate yard by a belt conveyor, and the tailings are pumped to the tailings pond. Equipped equipment: Thickener → Filter.
In this process, the phosphate is coated with a hydrocarbon. When bubbles move through the liquid, the coated particles attach to the bubbles and rise to the surface. This can be done a second time, but using a different hydrocarbon to attach to the sand. At this point, the sand, clay and phosphate have been separated.

Physical properties. Gypsum powder is a soft, white substance with a powdery texture. It is insoluble in water and has a slightly salty taste. The particle size of gypsum powder is often very fine, ranging from 1-100 micrometers. It is odorless and non-toxic, making it safe for use in many applications.
The recovery of better quality waste gypsum during acid mine drainage (AMD) neutralization is one step closer to achieving downstream waste gypsum beneficiation for recovery of valuable materials. This can facilitate recovery of treatment costs and prevention of environmental pollution from gypsum waste-dumps. Thermal reduction …
Final pH in the end of RIL process remained at pH = 0.98–1.03. pH is maintained mainly by protons that are released from the resin due to ion exchange. On the other hand, resin loading with the RIL method is slower than simple ion exchange in batch operation because dissolution of PG is slow. To ensure that equilibrium is nearly …
The beneficiation process enhanced the REEs from 200 to 240 mg/kg at a yield of 43%, with a subsequent reduction in the iron oxide content from 37.5 to 29.2%. Further, leaching efficiencies of REEs and impurity (Fe) co-extraction were studied before and after physical beneficiation. It is evident from the data obtained that upgrading …
Gold beneficiation is a process that involves two and a half stages of closed-circuit crushing, followed by two stages of closed-circuit grinding and flotation. Afterward, the selection process involves sweeping the tailings away through rough sorting operations. The selected tailings and sweep are combined with ore concentrate for regrinding.

Extracted ore, no matter the mineral, is typically first crushed, and then must go through a beneficiation process to remove the unwanted impurities. The beneficiation process can vary significantly from one ore type to the next. In most cases, however, beneficiation is carried out through a wet process that necessitates a subsequent drying step.
