Features

Improve gold recovery
Optimise adjustment of NaCN : DO Ratio
Reduce cyanide consumption
Increase throughput

Overview

On many gold plants, leach performance is directly determined by gold leach kinetics. Gold leach kinetics studies the rate at which gold dissolves from ore into a cyanide solution, providing crucial insights into the leaching process.

Residence times are limited, often due to throughput exceeding plant name plate capacity. Certain aspects of the leaching circuit need to be analysed to understand the hidden benefit in gold leach kinetics.

There are several reasons why customers should engage Molycop to undertake a gold leach kinetics project, including to:

determine if pre-oxidation will be beneficial
specify the right O2 and NaCN dosage/control equipment
size the O2 equipment correctly
adjust leach to optimal NaCN : DO ratio (for max kinetics)
select better setpoints for both DO and CN to optimise kinetics and reduce NaCN consumption
determine feed material O2 demand and CN demand
conduct scenario calculations (leach modelling) for different feed blends – current and future.

Typical Uses

Molycop’s gold leach kinetics service is used by metallurgists and process engineers in gold processing plants to optimise leach performance and improve gold recovery. By using the service to analyse critical factors such as pre-oxidation benefits, oxygen and cyanide dosages, and leach circuit adjustments, they can maximise kinetics, reduce cyanide consumption and efficiently process different ore blends.

Benefits

Increase gold recovery (1–5% range).
Optimise adjustment of NaCN : DO ratio.
Reduce cyanide consumption.
Increase throughput.
