Tailings Water Monitoring: A Procurement Guide for Mine Operators from Shanghai ChiMay Tailings storage facilities are now the single most scrutinized asset class on most mining sites. After the well-publicized failures of the last decade, regulators, insurers, and lenders have all converged on the same expectation: continuous, defensible water quality data from the tailings dam,…
Selecting Sensors for Acid Mine Drainage Neutralization: A Shanghai ChiMay Buyer’s Guide Acid mine drainage (AMD) is one of the most demanding water services in the mining industry. The combination of low pH, high sulfate, elevated heavy metals, and aggressive sludge means that the sensor selection decision made at procurement directly determines whether the neutralization…
Dissolved Oxygen Monitoring for Bioremediation of Mining Effluent: Engineering Notes from Shanghai ChiMay Biological treatment of mining effluent is no longer an experimental option. Sulfate-reducing bacteria for metals precipitation, nitrifying systems for cyanide and ammonia treatment, and aerobic biofilms for organic reagent destruction are all in commercial use at mines around the world. Every one…
Conductivity Measurement for Mineral Concentration in Process Water: The Shanghai ChiMay Approach Mineral concentration in mining process water has a direct impact on flotation recovery, leach kinetics, and downstream solvent extraction. Total dissolved solids, sulfate, and specific ions all influence the chemistry, and the simplest, most reliable real-time indicator of total ionic load is conductivity….
What Makes Real-Time Turbidity Monitoring Critical for Thickener Operations? Answers from Shanghai ChiMay A thickener is one of the most economically important pieces of equipment in any mineral processing plant. It decides how much water leaves with the tailings, how much is recovered for reuse, and how clean the overflow is when it returns to…
The Complete Guide to Mine Pit Dewatering Water Monitoring from Shanghai ChiMay Pit dewatering is the unglamorous backbone of every open-pit and underground mine. Without it, the working face floods, the haul roads soften, the slope stability falls, and production stops. With it, an enormous volume of groundwater flows through the operation every day —…
