Slurry characterisation

Evaluating the nature of mineral processing slurries, particularly pulp viscosity, is vital for the efficiency of any mineral processing and extraction plant.

Konnekta-mining designs programs of testwork to identify any slurry handling issues, and then systematically resolves them using specific techniques, reagents, and equipment.

Slurry characterisation test programs routinely carried out include:

  • Rheology

  • Particle Size

  • Pulp Density Determination

  • Solids Content

  • Liquid Content

  • Oxygen Uptake Rate Determination

  • Chemical or Reagent Content

  • Slurry Flocculation and Settling

  • Filtration

  • Transportable Moisture Limit (TML

  • will develop a practical scope of work to suit the project’s objectives. Data generated from slurry characterisation is often used to size-up specific equipment, such as pumps, slurry thickeners, and filters, and to meet environmental regulatory compliance requirements.

Gravity Separation 

Gravity separation is achieved based on the difference in specific gravity (SG), shape and particle size of the valuable minerals or metals, as compared with the gangue or host rock and the carrying medium.

Commonly performed techniques include:

  • Cyclone Separation

  • Dense Media Separation (DMS)

  • Ericson Cone Heavy Media Separation

  • Falcon Concentrator

  • Heavy Liquid Separation (HLS)

  • Jigging – Allmineral Alljig®

  • Kelsey Jig

  • Knelson Concentrator

  • Manual Panning

  • Spiral Rig

  • Superpanner

  • Teeter Column

  • Up-Current Classifier – Allmineral Miniflux®

  • Wilfley Table

A combination of gravity separation and other techniques often produces the desired result

Konnekta-mining provides gravity separation, in combination with other techniques, to identify and optimise the process flowsheet for the target mineral.

The mining industry landscape is evolving rapidly. There are fewer and fewer high-grade ore deposits, and they’re located in increasingly remote and challenging areas. To meet the ever-growing demand for resources, mining companies are forced to develop these once-overlooked deposits, which are more complex and expensive to retrieve. To top it off, environmental standards are more stringent than ever, new technologies are constantly being introduced, worker safety continues to be a critical issue, and societal concerns about mining continue to grow.

Put simply, the challenges can be endless. To guarantee the profitability and long-term viability of their projects, mining companies must therefore reinvent themselves by adopting best practices at every step of the project lifecycle.

Your challenges are complex…

To optimize the performance of your mine site and improve profitability, you need to focus on detailed planning and meticulous management of your existing assets. Whether your project is at the grassroots stage or you’re looking to increase the output of a mature operation, you must make decisions based on exhaustive analyses that are both detailed and reliable.

Your challenges:

  • Integrate strategic mine planning throughout the project lifecycle

  • Maximize the value of your project to meet or exceed stakeholder expectations

  • Preserve your social licence to operate

  • Reduce the project’s environmental footprint to ensure long-term sustainability
