Ore Blending
How stockpiles and feed planning can reduce abrupt changes in grade, hardness or mineralogy.
Where this fits
How stockpiles and feed planning can reduce abrupt changes in grade, hardness or mineralogy. The goal is to explain its place in the wider mine-to-metal system rather than turn the subject into an operating manual.
How the system works
A processing plant reduces and separates material so that a much smaller stream contains most of the recoverable gold. Ore mineralogy determines which combination of stages is suitable.
Important tradeoffs
Throughput, recovery and product quality trade off against one another. Increasing tonnes is not useful if liberation, separation or downstream capacity cannot keep pace.
What professionals monitor
Plants rely on measured flows, densities, sizes, assays and inventories. Recycle streams can make internal flow much larger than final output.
Lifecycle perspective
Tailings and water are major process streams and should be considered part of the plant rather than afterthoughts.
