Beach Sand Beneficiation Process

Beach sand, known as seashore placer, forms when heavy mineral debris accumulates in coastal areas due to the action of rivers, waves, tides, and ocean currents. It contains a complex composition of minerals such as rutile, ilmenite, magnetite, cobalt, monazite, and quartz sand. To separate these minerals, a combination of beneficiation processes including gravity, magnetic, and electric separation is required.

The process begins with gravity separation, where tailings are discarded, and rough concentrates containing ilmenite, magnetite, rutile, monazite, quartzite, and other minerals are obtained. Following this, the rough concentrates are further processed.

Electric separation is employed to separate qualified titanium concentrate, chromite, and monazite from the rough concentrates. This is done by leveraging the specific differences in magnetic or electrical properties that exist among the various components of the seashore placer rough concentrates obtained through gravity separation.

To effectively separate and enrich each component, a combined method involving magnetic separation, electric separation, and other beneficiation processes is commonly used. This allows for the efficient extraction and utilization of the valuable minerals present in beach sand.

Beach Sand Processing Plant

The beach sand processing plant has a capacity of 100 t/h and includes a complete configuration of the following equipment: a feeder for material intake, a vibrating screen for sorting, a belt conveyor for transportation, a slurry pump for fluid handling, a magnetic separator for separating magnetic minerals, a spiral chute for gravity separation, a shaking table for further separation, a rotary dryer for drying, and an electrostatic separator for additional mineral separation. This comprehensive set of equipment allows for efficient processing and extraction of valuable minerals from the beach sand.

The raw ore processing plant operates at a capacity of 100 tph. During the processing, any impurities with a size larger than 2mm are removed. The main objective of the plant is to effectively separate the minerals rutile, monazite, zircon, ilmenite, and magnetite from the beach sand.

Here is a reorganized description of the flowchart:

1. Raw ore is fed into the mine bin by an excavator or loader. It is then passed through the electromagnetic vibrating feeder and the vibrating screen with a 2mm sieve mesh layer to remove impurities above 2mm.
2. The material below 2mm is pumped from the slurry pump into the magnetic separator to separate the magnetite. The output from the magnetic separator is then sent to the spiral chute, where gravity separation removes light minerals.
3. The spiral chute has two stages. The middle ore from the first stage enters the second stage for reprocessing. All concentrate from the two-stage spiral chute is sent to the first double-drum magnetic separator to separate the ilmenite. The output is further processed on the shaking table, which removes light minerals through gravity.
4. The shaking table consists of eight sets and has two stages. The middle ore from the first stage is sent to the second stage for further processing. All concentrate from the shaking table is then sent to the rotary dryer for drying. The dried material is passed through the second double-drum magnetic separator to separate the ilmenite.
5. To separate rutile, other minerals from the second double-drum magnetic separator enter the first electrostatic separator. They then move to the second electrostatic separator to separate the rutile. The rutile is further separated in the third electrostatic separator. The remaining minerals are sent to the double-roller strong magnetic separator to separate zircon and monazite.
