Overview

Molycop’s industrial testing services provide customers with comprehensive froth flotation testing both on-site and in the laboratory to ensure optimal results in mineral processing. Molycop testing services enable the evaluation and comparison of frothers, indirect testing of depressants and the measurement of critical flotation parameters like bubble size distribution and superficial gas velocity, providing valuable insights to enhance flotation performance and efficiency.

Molycop conducts industrial testing for its customers to:

test and compare frothers
indirectly test depressants
measure bubble size distributions and superficial gas velocity.

Froth flotation instruments

Two instruments can be used for froth flotation testing purposes:

Bikerman: The Bikerman froth stability column can be used on-site and in the laboratory. The unit is used to test and compare frothers and collectors with frothing characteristics. The unit can also be used to indirectly test depressants if the gangue has froth stabilising characteristics such as talc and clays.

Bubble sizer: The bubble sizer is a portable device used to measure both bubble size distributions and superficial gas velocity – e.g. directly within a flotation cell.

It comprises a sampling tube attached to the bottom of a sealed viewing chamber. Bubbles from the pulp phase within the flotation cell travel in the sampling tube under non iso-kinetic conditions. The viewing chamber is made of plastic PVC with a single reinforced glass window.

A lighting array (LED lights within the viewing chamber) is used to ensure image contrast. The chamber is sloped (angle 15%) to spread the bubbles into a single layer to limit overlap and provide an unambiguous plane of focus. Digital photographs of the sample of bubbles are captured and then analysed with specialist image analysis software processes to derive the bubble size distribution.

Typical Uses

Molycop’s industrial testing services are used by process engineers and metallurgists to optimise froth flotation performance both on-site and in the laboratory. Molycop uses the Bikerman froth stability column to test and compare frothers, and the bubble sizer to measure critical parameters such as bubble size distribution and superficial gas velocity.

Benefits

Optimise frother selection: Test and compare frothers to determine the best options for froth stability and flotation performance.
Enhance reagent effectiveness: Indirectly test depressants and assess their impact on flotation efficiency.
Accurate flotation measurement: Measure critical parameters like bubble size distribution and superficial gas velocity, providing deeper insights into flotation dynamics.

Fosterville Gold Mine: Successful Deployment of Milling Optimisation Technology

Fosterville Gold Mine: Successful Deployment of Milling Optimisation Technology

Agnico Eagle Fosterville Gold Mine (Fosterville) operates a gold plant in Australia comprising of a crushing and grinding circuit (SAG mill with a closed loop cyclone classification circuit) followed by flotation, bacterial oxidation and leaching circuits. The lack of surge capacity between the grinding and flotation circuit and restrictions on crushing operations due to noise constraints resulted in unique set of challenges, that required the implementation of a novel control solution using advanced instrumentation.
