Gypsum ore dressing process

date icon

Gypsum ore dressing process is a complex and delicate process, which aims to increase the content of useful minerals in gypsum ore to meet different application requirements. It can be roughly divided into crushing-sorting-grinding-calcining. The following is a detailed overview of the gypsum ore dressing process:

The gypsum ore is first crushed by a crusher (such as a jaw crusher) to break it into small pieces that meet the requirements. This step is to facilitate subsequent treatment and processing.

Flotation

The flotation method uses the difference in physical and chemical properties between gypsum ore and impurities for sorting. During the flotation process, by adding flotation agents, the surface of the gypsum ore becomes aerobic, so that it floats to the surface of the slurry under the action of bubbles and is separated from the impurities. The flotation method is suitable for the sorting of fine-grained gypsum ore, but the selection and dosage of flotation agents have a great influence on the sorting effect.

Heavy medium ore dressing

The heavy medium ore dressing method is based on the difference in density between mineral particles for sorting. In heavy media (such as heavy liquid or heavy suspension), mineral particles of different densities are subjected to different buoyancy, thus achieving separation. Heavy medium separation is suitable for the separation of coarse-grained gypsum ores, but the equipment is complex and the operation is difficult.

According to relevant data, the motor power of shaftless trommel screens is usually smaller, which is one-half to one-third of other screen types. This means that when processing the same amount of material, the running time of the shaftless trommel screen is only half of other screen types, so the energy consumption is low. Specifically, if the energy consumption of…
