Technological process for selecting coastal sand mines

Beach sand ore is a common sedimentary mineral, mainly composed of quartz, feldspar, mica, etc., and also contains a small amount of heavy minerals. Mineral processing is the process of separating useful minerals from useless minerals in the raw ore, while the process of selecting coastal sand ore is the specific step of separating useful minerals from useless minerals in the raw ore. This article will introduce the process flow and operating steps of selecting seaside sand mines.

1、 The Properties of Coastal Sand Mines

Coastal sand ore is a sedimentary mineral containing a large amount of fine-grained minerals, with a particle size generally between 0.1mm-3mm. The useful minerals in seashore sand ores mainly include Ilmenite, Hematite, zircon, etc., of which Ilmenite is the most important mineral. The useless minerals in coastal sand mines mainly include quartz, feldspar, mica, etc.

II. Technological Process for Selecting Seashore Sand Mines

The process of selecting seaside sand ore mainly includes steps such as grinding, rough selection, selection, and tailings treatment.

1. Grinding

Grinding is the process of grinding the raw ore to an appropriate fineness for subsequent sorting operations. The main equipment for grinding ore includes ball mills, grinders, etc. During the grinding process, attention should be paid to controlling the grinding time and the use of grinding media to ensure that the mineral particle size produced is moderate.

2. Rough selection

Coarse separation is the preliminary separation of the ground raw ore, separating useful minerals from useless minerals. The equipment for rough selection mainly includes heavy medium sorting machines, vibrating screens, etc. During the rough selection process, attention should be paid to controlling the density of the sorting medium and the sorting time to ensure the sorting effect.

3. Selection

Selection refers to the further separation of minerals after rough selection, separating useful minerals from useless minerals. The selected equipment mainly includes heavy medium sorting machines, spiral sorting machines, etc. During the selection process, attention should be paid to controlling the density of the sorting medium and the sorting time to ensure the sorting effect.

4. Tailings treatment

tailings treatment refers to the treatment of selected tailings and the recovery of useful minerals. The equipment for tailings treatment mainly includes magnetic separators, heavy medium separators, etc. During the tailings treatment process, attention should be paid to controlling the density of the sorting medium and the sorting time to ensure the sorting effect.

3、 Conclusion

The process of selecting seaside sand mines is a complex process that requires mastering certain professional knowledge and skills. In the actual operation process, attention should be paid to controlling the operating parameters of each step to ensure the selection effect. At the same time, it is necessary to strengthen the maintenance and upkeep of equipment to ensure its normal operation.
