The strategy for supervisory control of grinding is to adjust the addition of water to the discharge sump of the mill and the cyclone
underflow. The operating parameters of the grinding circuit are governed by these variables.
We also present a histogram shifting technique to prevent overflow and
underflow.
Underflow from the thickeners is filtered in four 51 [m.sup.2] disc vacuum filters and dried in two fuel-oil rotary kilns.
The Water Leached Purification Residue (WLP) and the Neutralization
Underflow (NUF) are waste produced at the Lynas Advanced Materials Plant (LAMP) in Pahang.
In the proposed scheme sometimes there will be cases of overflow and
underflow of pixel values due to histogram shifting procedure, i.e.
Underflow from the cyclones is screened by banana screens and the undersize flows to six flash flotation cells which produce final grade concentrate.
The Department of Environment (DoE) has approved the Environmental Impact Assessment (EIA) report for Lynas to build a landfill to store its neutralisation
underflow (NUF) residue providing it fulfills 68 conditions.
The ground slurry from both the primary and regrind mills is pumped to cyclone classifiers, which produce a coarse
underflow fraction for regrinding and a fine overflow fraction for gold leaching.
