Electrochemical Turboreactors Flexicone for the oxidation of sulphide minerals and leaching of metals.
The reactor is designed to intensify chemical processes and more fully extract precious metals from refractory ores and concentrates, as well as sulfide and gold-silver tellurides minerals at normal atmospheric pressure and temperature.
Highest percentage extraction of gold from ores compare to other methods.
Non-hazardous , non-flammable chemical reagent - classification (000)
Leaching of noble metals takes place in less chemically aggressive conditions. Concentration and consumption of chemicals are reduced.
This is achieved due to the flow of the electrochemical process .
The possibility of stepwise leaching of metals.
Universality of technology and applicability for different types of ores and concentrates.
Simplicity of control and process control by voltage/current regulation on electrodes.
High wear resistance design, quick change and low cost of consumables.

1. Hardrock mining processing
Quartz ore with a sulfide content of up to 30% gold 5 g / t and silver 2 g / t crushed and milled to the size 0.1mm .
Milled ore processed through Flexicone Centrifugal concentrator to recover free gold and silver. Higher then 5% gold/silver content concentrate can be direct melted or purified with aqua regia.
Tailing from concentrate are being processed with Leaching Reactor FLR14
An aqueous 8% solution and crushed quartz ore with a sulfide content is poured into the apparatus . The ratio of T: W is 1: 1-1.5. The resulting pulp is processed for 180 minutes.
Gold and Silver leached from ore and in the same time are being precipitated. Then the pulp is filtered. The cake is washed with water and the resulting saline solution is again sent to leach the following material.
The degree of extraction of gold and silver is up to 99.8%
