Peek Valve Control in Cyclone Underflow DensityThe role of a peek valve in cyclone underflow density control is to regulate how quickly slurry leaves the hydrocyclone apex. Its position influences the size…
Selecting centrifugal pumps for high-head slurry transportHigh-head slurry transport places unusual demands on pumping equipment. The pump must generate sufficient pressure to move a dense mixture through long…
Gold elution circuit leaching: acid wash and carbon regeneration stepsA gold elution circuit removes precious metal from activated carbon after adsorption in a carbon-in-leach (CIL) or carbon-in-pulp (CIP) plant. The sequence…
Simulation software for designing a grinding and flotation circuitA grinding and flotation circuit must achieve several objectives at the same time: liberate valuable minerals, limit energy consumption, produce a stable…
Belt Conveyor Transfer Point Design for Cleaner, Safer Material FlowA conveyor transfer point is one of the most demanding areas in a mineral processing plant. Material changes direction, speed, and elevation while impact…
Magnetic Separation Routes for Hematite UpgradingHematite is a widely processed iron oxide, yet its recovery can be difficult when it occurs as a weakly magnetic mineral, is finely disseminated, or is mixed…
Copper flotation depression of pyrite using lime and cyanide alternativesSelective flotation is central to producing a saleable copper concentrate from sulfide ore. The challenge becomes sharper when pyrite is abundant, because…
Planning a second crushing stage for plant expansionAdding a second crushing stage can increase throughput, improve product sizing, and stabilize an expanding mineral processing operation. It also changes the…
Using density and flow meters to monitor mill feed in real timeStable mill feed is a foundation for predictable grinding, classification, and mineral recovery. When slurry density or volumetric flow changes unexpectedly,…
Ore Testing Protocol for Iron Ore Pellet Flowsheet DevelopmentA reliable pelletizing flowsheet begins long before the first green pellet is formed. The quality, mineralogy, moisture, and variability of the iron ore feed…
