Mining Chemicals

​

SENDACHEM's mining chemicals are developed to support efficient and reliable mineral processing operations. Properly selected reagents can help mining companies improve valuable mineral recovery, enhance separation selectivity, optimize reagent consumption, and maintain stable processing performance.

• Improve Mineral Recovery: Mining reagents can enhance the recovery of valuable minerals from ore by improving flotation, leaching, separation, and beneficiation performance.

• Enhance Mineral Selectivity: Selective collectors, modifiers, depressants, and other reagents help differentiate valuable minerals from gangue minerals, supporting improved separation and concentrate quality.

• Optimize Flotation Performance: Properly selected flotation chemicals can improve mineral-to-bubble attachment, froth formation, flotation kinetics, and overall recovery performance.

• Improve Process Efficiency: Optimized reagent selection and dosage can support more efficient mineral processing while helping reduce unnecessary chemical consumption and processing losses.

• Maintain Consistent Concentrate Quality: Stable reagent performance helps mining operators maintain consistent recovery and concentrate specifications despite variations in ore characteristics and operating conditions.

• Support Cost-Efficient Mining Operations: Effective reagent management can help reduce chemical consumption, mineral losses, reprocessing requirements, and other operational inefficiencies.

• Support Sustainable Mineral Processing: Optimized mining chemical usage can contribute to improved resource recovery, reduced process waste, efficient water management, and more sustainable mineral processing operations.

SENDACHEM Singapore supplies a range of mining chemicals and mineral processing reagents for flotation, beneficiation, leaching, and mineral separation processes.

1) Flotation Collectors

Flotation collectors are reagents used to selectively modify mineral surfaces and increase the hydrophobicity of target minerals. This promotes attachment between valuable mineral particles and air bubbles during froth flotation, helping improve mineral recovery and separation efficiency.

SENDACHEM provides collector solutions for different ore types and flotation systems, with reagent selection based on mineralogy, target minerals, pH conditions, water chemistry, and required recovery performance.

 

 

 

2) Flotation Frothers

Frothers are mining chemicals used to control bubble formation and froth characteristics during mineral flotation. Suitable frother selection can help produce a stable and controllable froth layer, supporting effective mineral recovery and improved flotation performance.

SENDACHEM's frother solutions can be selected according to flotation conditions, ore characteristics, equipment configuration, and desired froth behavior.

 

 

 

3) Flotation Modifiers & Depressants

Flotation modifiers and depressants are used to control mineral surface interactions and improve the selectivity of flotation circuits. These reagents can help promote the flotation of target minerals while suppressing unwanted minerals or gangue materials.

SENDACHEM provides modifier and depressant solutions for complex mineral processing applications where selective separation and concentrate quality are important.

 

 

 

4) Leaching Chemicals

Leaching chemicals are used in hydrometallurgical processes to dissolve target metals from ores, concentrates, or other mineral-bearing materials. Appropriate leaching chemistry can support efficient metal extraction while taking into account ore composition, mineralogy, process conditions, and downstream recovery requirements.

SENDACHEM provides chemical solutions for specific leaching applications and can support reagent selection based on the customer's process requirements.

 

 

 

5) Mineral Beneficiation Chemicals

Mineral beneficiation chemicals support the upgrading and concentration of valuable minerals through processes such as flotation, selective separation, and other beneficiation technologies.

These solutions can help improve mineral recovery, concentrate grade, separation efficiency, and overall beneficiation performance across different ore types.

 

 

 

6) Mineral Processing & Water Treatment Chemicals

SENDACHEM also provides chemical solutions for supporting mineral processing operations and process-water management, including applications related to solid-liquid separation, clarification, suspended solids control, and water reuse. Chemical selection can be tailored to the characteristics of the ore, process water, treatment system, and operational requirements.

SENDACHEM's mining chemical solutions are applicable across major stages of mineral processing:

• Froth Flotation: Flotation collectors, frothers, modifiers, and depressants are used to improve mineral recovery, flotation selectivity, froth stability, and concentrate quality.

• Ore Beneficiation: Chemical solutions support the concentration and upgrading of valuable minerals from run-of-mine ore and processed mineral streams.

• Selective Mineral Separation: Specialized reagents help separate valuable minerals from gangue or other minerals with similar physical or chemical characteristics.

• Hydrometallurgical Leaching: Leaching chemicals support the dissolution and extraction of target metals from suitable ores and concentrates.

• Mineral Concentration: Chemical solutions can improve the efficiency of mineral concentration processes and help optimize valuable mineral recovery.

• Process Water Treatment: Chemical solutions support clarification, suspended solids removal, water quality management, and process-water reuse within mining operations.

• Tailings & Process Optimization: Appropriate chemical selection and dosage can help reduce mineral losses, improve process efficiency, and optimize overall plant performance.
