HiGrade Technik provides practical advice and support for gravity recovery projects.

Typical applications include tin, tungsten, tantalum, chrome, copper, gold, silver.

Solutions

Ore Characterization

Assess mineral / metal characteristics based on specific gravity, breakage, liberation size, and shape to determine selective recovery pathways. For mineral applications, heavy liquid separation (HLS) can be a low cost benchmark qualifier, requiring only small sample volumes.

Gravity Recovery Testwork

Support the execution of metallurgical testwork on a wide array of gravity recovery methods, including batch / continuous discharge type centrifugal concentrators, shaking tables, spirals or mineral jigs

Flowsheet / Plant Design and Mass / Metal Balance

Develop practical flow sheets and establish realistic production expectations, based on metallurgical response and economic / geographic environments. Evaluate proven equipment solutions.

Commissioning Support

Support operations in reaching steady state performance, while identifying, recording and resolving process bottlenecks

Performance Benchmarking and Optimization

Measure process performance against established benchmarks and evaluate optimization strategies.

Reporting

We take pride in concise reports that capture the essence of the task and focus on the solution.
