flow process and rheology center in mining

Flow Process and Rheology Centre (FPRC) CPUT

What is the Flow Process and Rheology Centre (FPRC) all about?We solve problems that relate to the flow of industrial fluids. Typically our work ranges from mining slurries and paste & thickened tailings, to explosive emulsions, foodstuffs, pharmaceuticals, flowable concrete and cosmetics. Our expertise lies in making precise measurements of the viscous characteristics [called “rheology

Process Control in Mining The Role of Rheology

In this way the effectiveness of different processes (or process additives) can be observed e.g. localised testing of the process of flocculation. Using these well accepted measurement techniques can help the mining industry effectively control their processes and maximise returns.

The Importance of Rheology in Mining Processes

Aug 26, 2019· The rheology of tailings flow, like the creep and failure of mine walls and failures, can be modeled numerically; however, the nature of the wastes can be complex. Their behavior following dam breach can, therefore, be characterized as highly-viscous debris flows or muddy floodwaters.

Rheological investigation in the mining and oil

Rheological measurements provide important information about the efficiency of the processes described above, which largely revolve around the flow of slurries and liquids: . Drilling. Drilling fluids play a number of important roles in the drilling process, such as lubricating the bit and drill string, clearing cuttings from the bit face, and keeping formation fluids at bay.

Use Rheology and Flow Simulation to Troubleshoot Extrusion

Jan 11, 2021· Rheology is the science related to how materials flow. Its usefulness is well known by most extrusion and injection molding equipment designers. For example, viscosity curves as a function of shear rate and temperature are used to calculate pressure drop in an extrusion die and, ultimately, to dimension the flow channel for a particular set of

Rheology 101 Learning the Basics

The term rheology, as with most scientific fields, has its roots in Ancient Greek with the stem rheo meaning ‘flow’ in English. As the field has advanced it is no longer just concerned with the flow of liquids but also the deformation of solids and the complex behavior of viscoelastic materials that have the properties of both liquids and

The Centre for Industrial Rheology

"The Centre for Industrial Rheology’s value lies in their ability to offer sound technical advice on the development of practical and appropriate test methods to suit specific needs. Their work for our group resulted in a test method that has been extensively employed for process development and scale-up prior to transferal to our production

Effect of froth rheology on froth and flotation

Jan 01, 2018· If the flow index can be considered constant, the variation of froth rheology in these tests can be represented by the differences in the consistency indices (μ). In order to validate this hypothesis, the authors ( Li et al., 2016b ) statistically analysed and proved that the flow index could be treated as a constant in this work, and the

Mineral processing Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

Fold (geology) Wikipedia

In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation.Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur as single isolated folds or in periodic sets (known as fold trains).Synsedimentary folds are those formed during sedimentary deposition.

Rheology & Viscosity Testing & Profiling Techniques & Methods

Rheology Model Fits for Pump-sizing and Process Design. A range of rheological models can be fitted to quantify flow curves and obtain parameters for inputting into process design and engineering calculations. These models are typically fitted to shear stress/shear rate flow curves or viscosity/shear stress or viscosity/shear rate profiles.
