1 General Albion Process Description - Core Resources

The Albion Leach Reactor is agitated using dual hydrofoil impellers and oxygen is introduced to the leach slurry at supersonic velocity to improve mass transfer efficiency and ensure efficient oxidation of the sulphides. The Albion Leach Reactor is designed to operate at close to the boiling point of the slurry, and no cooling is required.

Improving the gold leaching process of refractory ores using the ...

After 24 h leaching, a maximum gold recovery of 81.70% was obtained with the conventional method and 74.36% with the bottle roll whilst 91.28% gold recovery was obtained using the Jetleach reactor. This is an improvement of almost 10% and 17% compared to the conventional and bottle rolling methods respectively.

Atlantic Gold Moose River Paper - Sepro Mineral Systems Inc.

The Sepro Leach Reactor (SLR) is a batch, intensive leach reactor specifically designed to rapidly leach high-grade gravity concentrates with high concentration cyanide solution. The SLR uses an agitated leach vessel for increased leach kinetics and Sepro's patented filtration system to produce clear pregnant solution for direct electrowinning.

Precious Metal Ore - an overview | ScienceDirect Topics

The oxygen used for oxidation is injected into the base of the Albion leach reactor at supersonic velocity to achieve the required mass transfer and leaching rate. Chalcopyrite is acid leached through ferrous ion oxidation (Fe 3+ being the main oxidizing agent) by oxygen according to the mechanism suggested by Hiroyoshi et al. (2001) in Eqs.

Tank leaching - Wikipedia

Tank and vat leaching involves placing ore, usually after size reduction and classification, into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution. In tank leaching the ground, classified solids are already mixed with water to form a slurry ...

Process Data Sheet – Agitated Reactor - ChemEnggHelp

Agitator types and their Utility As we discussed agitator role is to provide turbulency inside the agitated reactor. Therefore, type of agitator selection depends on process requirement and viscosity of the fluid. Apart from this presence of suspended solid catalyst and gas feed also crucial for the agitator selection.

Agitator Speed - an overview | ScienceDirect Topics

A gate type anchor agitator is shown in Figure 5.6.Anchor agitators operate within close proximity to the tank wall. The shearing action of the anchor blades past the tank wall produces a continual interchange of liquid between the bulk liquid and the liquid film between the blades and the wall [Holland and Chapman (1966)].Anchors have successfully been used to mix liquids with dynamic ...

OKTOP® Agitators - Outotec

The Outotec OKTOP® Agitators enable reliable and efficient operation in demanding mining, minerals processing and metallurgy applications. Agitators are used in various mixing, solids suspension and gas dispersion duties and are used in both in atmospheric reactors and autoclaves.

Improving the gold leaching process of refractory ores using the ...

The Albion process is an atmospheric leaching process for processing zinc concentrate, refractory copper and refractory gold (Joe, 2005). This process is an integration of the Ultra-fine grinding (UFG) and oxidative leaching at atmospheric condition (Mike Hourn, 2014).

Laboratory Leach Reactor - 911Metallurgist

Built-in thermometer which displays the temperature of slurry undergoing leaching. Built-in 250 Watt heater and temperature controller (50 Celsius) for your leach slurry. Comes standard with 1.5 liter, 3 litre and 5 liter plastic leach tanks. Three (3) size agitators of 31 mm, 39 mm and 48 mm diameter are included with the laboratory leach reactor.

Albion amenability testwork was undertaken to determine whether the process should be considered as part of the next phase of testwork. The Neutral Albion Leach testwork was done to target 60- 75% sulphide sulphur oxidation. The testwork involved ultrafine grinding to around 10μm, acid addition to get the process started and

Leach Reactors for intensive cyanidation of gravity gold concentrates. These include both batch and continuous units. While Batch Inline Leach Reactors are cost ef- fective for small concentrate masses, higher feed rates require a continuous reactor. Significant gravity recovery improvements For this process to be viable it is necessary to reliably

The Albion Process for Refractory Gold - Core Resources

Solid Liquid Separation and Leach Tailings Stability The Albion leach is typically operated at a slurry density of 25 – 35% w/w, depending on sulphide levels in the concentrate. The discharge pH from the Albion leach is raised to 8 – 10 in the final Albion leach tank to further break down any sulphate phases prior to the cyanidation stage.

Tank leaching - Wikipedia

Dissolved gas - Gas is often injected below the agitator or into the vat to obtain the desired dissolved gas levels – typically oxygen, in some base metal plants sulphur dioxide may be required. Reagents - Adding and maintaining the appropriate amount of reagents throughout the leach circuit is critical to a successful operation.

Multi-agitator mixer/reactors - ROSS Mixers

Multi-shaft mixers are composed of two or more independently-driven agitators working in tandem. A low-speed anchor agitator complements one or two high-speed devices such as a saw-tooth disperser and/or a rotor/stator mixer. In combination, these mixing elements can handle viscous reactants that are several hundred thousand centipoise.
