Internal Laboratory

JRI’S Internal Laboratory utilizes state of art amperometric and mass spectrometric analytical analysis equipment to assess the presence and concentrations of potentially hazardous materials such as cyanide and mercury within mining by-products, ensuring a safe work environment along with proper, ethical waste management strategies.

Mercury Monitoring

Just Refiners has carried out extensive research and monitoring on spent carbon with various levels of mercury. Every stage of the carbon treatment at JRI is monitored for mercury.


At no stage has any high levels of mercury been detected throughout the JRI carbon treatment process. The JRI laboratory analysts takes vapor samples at random. Each mercury reading is recorded and filed away for due diligence and control purposes.


Occasionally, the mercury monitor records a spike in the mercury readings but this spike is directly related to elevated temperatures in and around some of the processing equipment. (We have proved it is not mercury but temperature.)

JRI will now be able to run scans for deleterious elements with the purchase of the following instruments:


AA: Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state.


In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed.

ICP-OES: Inductively coupled plasma atomic emission spectroscopy


(ICP-AES), also referred to as inductively coupled plasma optical emission spectrometry


(ICP-OES), is an analytical technique used for the detection of chemical elements.
