Filed: 1999-08-12
Abstract: In a BAYER circuit, a process for controlling precipitation in which particle size quality of alumina hydrate produced in the circuit and circulating in feed tanks is monitored utilizing a calibration step and a control step. In the calibration step, cumulative percentage of alumina hydrate particles circulating in the feed tanks in the circuit that are finer than X2 mum, defined as CPFT X2, is measured vs. time and cumulative percentage of alumina hydrate particles circulating in the feed tanks in the circuit that are finer that X1 mum, defined as CPFT X1 vs. time, is measured, where X1 and X2 are predetermined particles sizes and X1 is smaller than X2. A relationship R between CPFT X1 and later changes in CPFT X2, is determined and upper and lower trigger thresholds of CPFT X1 which correspond to maximum permissible variation in CPFT X2 are defined. In the control step, CPFT X1 and CPFT X2 are regularly measured, and R and the correlation between CPFT X2 and the particle size of hydrate produced are updated. Corrective action is taken at the beginning of precipitation when the measured value of CPFT X1 reaches one of the trigger thresholds.

Title: Gas-phase modification in earth materials
Inventor: HARRINGTON JOSEPH G
IPC: B09B1/00
Filed: 1999-11-04
Abstract: A process for treating earth materials such as rock heaps to prevent acid rock drainage therefrom is disclosed. First, the oxygen concentration in the gas-phase of the rock heap (40) is decreased, that is, displaced and/or depleted. This first step may be accomplished physically, chemically or biologically. Then, the gas-phase oxygen concentration in the heap (40) is maintained at a low level. This second step may be provided for in a self-sustaining manner, like, for example, by covering the rock heap (40) with soil and vegetation so that acid rock drainage is prevented indefinitely. Alternatively, the density of the gas-phase of the rock heap (40) may be increased, and maintained at an elevated level indefinitely. The process is applicable to waste heaps from mining and industrial operations such as power generation and minerals processing, and to rubble collections in open and closed mines.
