MHC™ Series hydrocyclones are an optimal choice for wet classification in mining. They provide higher separation efficiency and increased uptime.
Pilot-scale tests indicate that effective concentration of fine gold from Colorado River sands can be achieved by flotation with the air-sparged hydrocyclo.
Through the demonstrated hydrocyclone electrowinning test, the gold concentration could be decreased from 100 to 0.24 mg·L −1 within 12 h while destroying almost total amount of free cyanide in a day.
The Hydrocyclone Efficiency Curves are affected by many operating factors such as feed density, apex and vortex sizes and feed pump pressure. These factors will cause your cyclone classification to operate correctly, in roping or spraying mode. Everyone knows or has seen an "Ideal Cyclone Efficiency Curve" VS an actual real life …

Minerals Africa introduces a state-of-the-art 20-way ® hydrocyclone cluster, promising unparalleled efficiency and durability in gold processing.
A hydrocyclone is a simple cone-shaped cylindrical container that has no moving parts. It is used to separate or "cut" solid particles in a liquid stream by size and density. What does a hydrocyclone look like? A hydrocyclone consists of a cylindrical top with an offset feed inlet pipe, an overflow outlet on top and tapered cone(s) leading ...
Emerson mining controls experts develop hydrocyclone separation optimization technology for me efficient & reliable operations.
The hydrocyclone is used to classify the coarse particles of the tailings. The classification efficiency is high, the processing capacity is large, and the operation flexibility is well, which reduces the waste of resources to a certain extent. In order to improve the recovery rate, a gold ore flotation plant uses a hydrocyclone for classification.
Then this chapter comprehensively reviews the hydrocyclone-separation technologies developed by geometric parameters, operating parameters, and operating conditions, the challenges and perspectives. It is hoped that this chapter will significantly improve the recovery-and-reuse effectiveness of various solids, liquids, gases, and energy by ...
Operation parameters restrict the performance of hydrocyclone in offshore platforms. Based on the computational fluid dynamics (CFD) software Fluent and the similarity parameter criterion experiment, the numerical simulation of the separation flow field and separation efficiency of hydrocyclone at different feed solid concentration was …
Pilot-scale tests indicate that effective concentration of fine gold from Colorado River sands can be achieved by flotation with the air-sparged hydrocyclone. The fine sands (55% −400 mesh and 0.01 opt*) from gravity concentration were processed with a 5-cm air-sparged hydrocyclone (capacity ~1.0 t/h dry solids). Concentrate grades as high as 5.0 opt were …
Hydrocyclones are used in desliming, degritting, concentration, recovery of solids, clarification, open-circuit classification, and closed-circuit grinding. The hydrocyclone below is used to remove polypropylene powder from a solvent recovery unit.
Here is a hydrocyclone sizing calculator with immediate access to all design equations needed for your hydrocyclone design calculation in an online XLS spreadsheet format.
The ® 650CVX hydrocyclone was selected as it is capable of handling the feed volumes and achieving the required cut point at corresponding pressures as per …
The authors also cover the fundamentals hydrodynamics of solid–fluid interaction with application to the fluids and suspensions flow of in circular pipelines and discusses the flow pattern in hydrocyclones from a fluid dynamics point of view. The physical design, the empirical, phenomenological and numerical hydrocyclone models are presented.
The key when selecting a hydrocyclone is to avoid focusing too narrowly on the equipment itself. If one does not factor in the entire process, the margin of error will …

Through the demonstrated hydrocyclone electrowinning test, the gold concentration could be decreased from 100 to 0.24 mg·L⁻¹ within 12 h while destroying almost total amount of free cyanide in ...
Hydrocyclones demonstrate a trait that is useful for gold mills—minerals with higher specific gravities have a progressively finer cut-size (whether this is desired or not).
Hydrocyclones used for solid–liquid separation are usually composed of a single cone. In this paper, we designed hydrocyclones with two cone combinations for solid–liquid separation and studied the flow field and separation performance.
