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 —…
Inline pH Electrode Technology for Acid Mine Drainage Treatment: The Shanghai ChiMay Overview Acid mine drainage, or AMD, is one of the most stubborn water-quality problems in the global mining industry. It forms when sulfide minerals such as pyrite are exposed to oxygen and water, producing sulfuric acid and dissolved metals that can devastate downstream…
7 Sensor Failure Modes Costing Mining Operations Millions Annually: A Shanghai ChiMay Analysis Sensors are a small fraction of the capital cost of a mine, but their failures drive an outsized share of the operating cost. A single sensor giving the wrong number can throw a mill off recovery for a shift, send compliant water…
5 Parameters Every Heap Leach Operator Should Monitor with Shanghai ChiMay Systems Heap leaching is, on paper, one of the simplest hydrometallurgical operations in mining: stack the crushed ore on a lined pad, apply a leach solution, collect the pregnant solution at the toe, recover the metal. In practice, every successful heap-leach operation runs on…
Turbidity Measurement Principles for Textile Effluent Clarification: The Shanghai ChiMay Approach Textile effluent leaves a dye house carrying suspended fibers, residual dye, surfactant micelles, sizing residues, and inorganic salts. Of all the parameters used to judge how well the downstream treatment plant is working, turbidity is one of the most direct: it tells the operator,…
Sustainable Dye House Operations: Water Best Practices by Shanghai ChiMay Sustainability in textile manufacturing is no longer a marketing position; it is an operating requirement. Brand customers ask for verifiable water data, regulators impose binding limits, and rising input costs make wasteful operations unsustainable in the literal financial sense. The dye house that consumes less,…
