Antimony Ore Beneficiation Solutions

Program Overview

As an important non-ferrous metal mineral resource, antimony ore beneficiation process has a direct impact on resource utilization rate and economic benefits. This solution adopts "re-election - flotation combined process", giving full play to the respective advantages of re-election and flotation, and realizing the efficient recovery of antimony ore. The antimony ore beneficiation process is characterized by energy saving and environmental protection, strong adaptability, high recovery rate, etc. It is suitable for the separation of various types of antimony ores.

Process flow details

Preparation stage before beneficiation

Crushing and screening system:

• Coarse crushing: Jaw crusher is used to crush the raw ore to less than 30mm.

• Fine crushing: use cone crusher to control the final product size.

• Grading: 8-30mm, 2-8mm, 0-2mm grades

Pre-sorting operation (optional)

• Manual picking of lumpy rich ore to increase the inclusion grade

• Photoelectric sorting technology to realize automatic pre-sorting.

Re-election system (core process)

Jigging sorting process:

• AM30 jigger: processing 8-30mm coarse-grained ore

• LTA1010/2 jigger: processing 2-8mm medium-grained ore

• Sawtooth wave jigger: processing 0-2mm medium and fine grained ores

Concentrate processing:

• Mixed concentrate enters the concentrate zone

• Can be directly used as final product or further processed

• Concentrate grade up to 30-45%

Flotation system (purification process)

Grinding and Classification:

• Re-grinding of the re-selected tailings

• Control the flotation feed particle size of -0.074mm 75-85%

• Adopt ball mill and cyclone group closed-circuit grinding.

Flotation process:

• First roughing operation: rapid capture of antimony minerals

• Three concentrates: gradually increase the grade of concentrate to 55-60

• Two sweeps: maximize the recovery of useful minerals

• Use of special antimony ore collector and adjusting agent

Shaking table sweeping:

• Recover fine-grained antimony oxide minerals

• Increase the comprehensive recovery rate by 3-5

• Complementary to the flotation process

Product Processing System

Concentrate dewatering:

• Concentration using high efficiency thickener

• Dewatering by plate and frame filter press

• Concentrate moisture control below 12

Tailings treatment:

• Tailings are transported to tailings storage

• The recycling rate of return water reaches more than 90%

• Realize zero wastewater discharge

Key Equipment Configuration

Technical Advantages

High-efficiency recovery technology

• Pre-enrichment by re-election, increasing the grade by 20-30%.

• Fine purification by flotation, concentrate grade can reach 55-60%.

• Comprehensive recovery rate can reach 85% or more

• Adopting multi-stage classification and sorting, the recovery rate can be increased by 5-8%.

Energy saving and environmental protection

• No chemicals are added to the re-election section, environmentally friendly.

• Low consumption of flotation chemicals reduces production costs.

• Tailings treatment meets the standard, which is in line with environmental protection requirements

• High recycling rate of water resources

Strong process adaptability

• Can process all kinds of antimony ores (oxidized ore, sulfide ore)

• Wide range of particle size (0-30mm)

• Flexible adjustment of the process according to the nature of the ore

• Adaptable to different production scale requirements

Remarkable economic benefits

• Short payback period, usually 1.5-2 years

• Low operating cost, excellent energy consumption index

• High resource utilization rate, good return on investment

• High degree of automation, low labor costs
