Electrochemical turbo-reactors Flexicone 3-in-one for the oxidation of sulfide minerals, leaching of gold and platinum group metals and filtration of ultrafine suspensions.
Flexicone Ultrasonic cavitator enhances chemical processes

Flexicone KNOWHOW reactors are universal devices 3 in one designed to carry out the entire complex of chemical processes:

1.opening refractory gold, sulfide and gold-silver telluride minerals at normal atmospheric pressure and temperature (KNOWHOW)

2.processes of leaching of gold, silver and platinum group metals and more complete extraction of precious metals from refractory ores and concentrates (KNOWHOW)

3.High-speed filtration and washing of ultrafine suspensions (KNOWHOW)



Versatility of application for different leaching technologies

Chemical resistance to acidic and alkaline solutions

High-speed and more complete filtration and washing of fine slime suspensions without the introduction of coagulants

Highest gold recovery from refractory ores compared to other suppliers

Non-hazardous, non-flammable chemicals - classification (000)

Complete regeneration of reagents.

Leaching of precious metals occurs in less chemically aggressive conditions.

This is achieved through an electrochemical process.

Possibility of stepwise leaching of metals.

Versatility of technology and applicability for various types of ores and concentrates.

Easy to monitor and control the process by regulating the voltage / current on the electrodes.

High wear resistance, quick changeover and low cost of consumables

Possibility of quick and differential colorimetric control of gold, silver and PGM content in solution

from 0.25mg / liter

Case studies:

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%
