Impact of COVID-19 on gold mining 

Half of 2020 has passed – An extraordinary year where an unexpected pandemic has impacted almost every market and industry. And mining is no exception. Some mine operations were impacted through government-mandated shutdowns like in South Africa and Peru, while others are operating at a cautious rate. Not only are production expectations under pressure, some gold mining companies are forced to review process structures and implement performance-oriented solutions.

Cyanide is one of the most common commercially used and efficient reagents to leach gold. However, many mine operators still struggle to efficiently manage their cyanide concentrations due to limitations of traditional measurements methods such as manual titration. Challenges in measurements range from user bias, unknown interference in the samples, to errors in calibration and extensive maintenance of equipment. To help mine operators understand where they stand with regards to their current cyanide monitoring process, here is a checklist we have developed based on our experience working with mine operators.

The framework focuses on neuralgic points in the cyanide monitoring process where users can understand whether they might require strategic overhaul or if process can be fixed with immediate measures. Going through this list not only helps to highlight causes for elevated variability in measurements but also allows mine operators to understand where they need to take action and close the gaps with respect to cyanide consumption, gold recovery rates and turnaround time for corrective actions. When all items along the checklist can be answered with “YES”, you are right on track with your cyanide monitoring process.

Gather ACTUAL data on your cyanide levels onsite

Themain goal of the pilot program is to allow gold mine operators toevaluate the impact of our cyanide control solution at their own site and establish cost-saving results for their process. CyanoGuard’ssolution is less susceptible to interference, less prone to measurement errors andproduces results with lower variability when compared with traditional titration methods. There is no maintenance, calibration orcapital investment required. During the period of approximately four weeks, you will ultimately gain clarity on your cyanide usage and concentrations in your process. We will provide you with the product kit, remote onboarding and web training for your operators. Rest assured, you will get our dedicated support during the pilot project.

When less (cyanide) is more: Challenges in cyanidation of gold

Jun 4, 2020 / by CyanoGuard posted in rising cyanide cost, responsible mining, improve gold recovery, cyanidation of gold, detoxification reagent cost

In the last 30 years, cyanidation of gold has been increasingly more difficult as a result of various key drivers such as declining ore grade, increasing complexity of treatment processes, rising pressure from investors and general public on reducing environmental impact of mining and rising cyanide cost. The common dilemma of most mine operators is to apply excess amounts of cyanide to ensure that all gold is properly dissolved. Yet on the other hand, this also means more cyanide cost, detoxification reagent cost, water consumption and environmental impact. In the late 1980s, efforts to introduce an online cyanide analyser were made but progress has been slow. Not only do most cyanide monitoring technologies today require extensive expertise to operate, they are often not real-time, and results can be highly unreliable.
