Oceanside Alluvial Beneficiation Solutions

Solution Overview

Seaside sand ore is rich in ilmenite, zircon, rutile, monazite and other high-value heavy minerals, and is a mineral resource with important economic value.Based on decades of accumulation of gravity beneficiation, magnetic separation and electrostatic separation technology, GravityMineral has developed a mature "gravity beneficiation pre-enrichment - magnetic separation step-by-step - electrostatic separation depth purification" joint process solution for the characteristics of Seaside sand ore. The program is based on the characteristics of seashore sand ore. This beach sand ore beneficiation program scientifically utilizes the differences in density, magnetism and electrical conductivity of minerals to realize the efficient recovery of various valuable minerals, which has the significant advantages of stable flow, strong adaptability, high recovery rate, environmental protection and energy saving.

Complete process flow

1. Pre-treatment section

Sieving and grading:

• Adopting double-layer tumbler screen, the upper layer removes coarse impurities such as shells and gravel.

• The lower layer ensures the effective minerals to enter the subsequent process, avoiding the waste of resources.

• High-pressure water gun rinsing to remove clay and organic impurities thoroughly.

2. Roughing enrichment section

Pre-enrichment of gravity separation:

• The spiral chute group carries out preliminary enrichment, utilizing the difference in specific gravity of minerals to obtain heavy sand rough concentrate.

• Shaking table sorting to further increase the concentrate grade, by adjusting the stroke to adapt to different mineral characteristics

Wet magnetic separation:

• Preliminary separation of magnetic (ilmenite) and non-magnetic minerals by a medium-strength magnetic separator.

• The magnetic field strength can be adjusted to ensure the best sorting effect.

3. Selection and purification section

Drying process:

• Indirectly heated dryer with precise temperature control (80-120°C).

• The surface properties of the minerals are preserved, creating optimal conditions for subsequent sorting.

Dry magnetic separation:

• Multi-roll magnetic separator realizes the graded separation of ilmenite and improves the concentrate grade.

• Zircon ore special magnetic separator for zircon's weak magnetic characteristics of efficient separation.

Electrostatic purification:

• High-voltage electrostatic separator utilizes the difference in electrical conductivity to separate rutile and zircon

• Arc plate electrostatic separator ensures the separation precision and recovery rate through 4-5 layers of separating plates.
