SAG Mill Control: It Shouldnt be that Hard

SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill and/or manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill ...

 · Froth flotation is a complicated process which is difficult to establish its first-principle model. Due to the fluctuations in the grade of raw ore, adaptively adjusting the set-points is extremely important in the flotation process. The inappropriate set-points easily lead to the instability of the process. This paper presents a fuzzy association rule-based set-point adaptive optimization and ...

Gold Report

"As long as gold and the gold ETFs remain below the 150-day moving average the bears can claim control over the intermediate-term trend. A close above the 150-day moving average, however, would set up a retest of the late August high and would be an inviting target for the bulls to complete a bottoming pattern that was begun four months ago."

Silver Gold Recovery Flotation Process

 · The ore is ground to 65 mesh, 55% being minus 200 mesh, in five tube mills, each in circuit with a " Sub-A" Cell and a Dorr Classifier. A xanthate mixture is added with some aerofloat to the mills, and 75% of the precious metals is recovered from the flotation cells by the method already described.

Optimisation of gold recovery by selective gold flotation …

Abstract. Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides.

Copper Sulfide Flotation

 · Standard "Sub-A" Flotation Machines are used for both the rougher and cleaner circuits, where their cell-to-cell principle gives both high recovery and a good grade of concentrate. The rougher concentration is accomplished in 6 or 8-cell flotation machines, with the concentrate from each going to a separate bank for cleaning and re-cleaning.
