Selecting Sensors for Acid Mine Drainage Neutralization: A Shanghai ChiMay Buyer’s Guide

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…

Water Reuse vs. Freshwater in Mining Operations: A TCO Analysis from Shanghai ChiMay

Water Reuse vs. Freshwater in Mining Operations: A TCO Analysis from Shanghai ChiMay Water is no longer an unlimited input on a modern mining site. In arid mining regions, the freshwater allocation may be the binding constraint on production, and even in water-rich jurisdictions, the cost of permitting and infrastructure for freshwater abstraction has risen…

Turbidity Control for Thickener Overflow in Mineral Processing: A Shanghai ChiMay Field Guide

Turbidity Control for Thickener Overflow in Mineral Processing: A Shanghai ChiMay Field Guide The thickener is the unsung workhorse of mineral processing. It separates fine solids from process water, produces underflow that goes to filtration or tailings, and produces overflow that returns to the mill as recycle water. The overflow turbidity determines whether the recycle…
