what is low failure rate ore processing plant

Sep , failure exists in varying degrees eG partial or total failure but in the most basic terms, failure simply means that a system, component, or device can no longer produce specific desired results even if a piece of manufacturing equipment is still running and producing items, it has failed if it doesnt deliver the expected quantities
