Using Laboratory bench-top float test results and their retention (flotation) time to scale-up to real life full scale plant time can be done using the following tables and examples. How to select the proper scale-up factor takes experience and …. good data. Figure 16.7 was used and seen in the a technical report for the Pebble ...
Assaying Antimony. To determine the amount of antimony in an ore containing sulphide of antimony and more or less vein- stuff:— Place about 2,000 or more grains of broken-up ore in a crucible, the bottom of which is perforated, and the hole in which is partially closed by a small piece of charcoal.
Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.

3. Bulk Flotation. bulk flotation of antimony ore. Bulk flotation is a method where all sulphide minerals are floated together. They are then separated into valuable minerals and gangue minerals ...
The frequent changing of ore properties is a significant issue, which causes difficulty in many flotation plants because good ore resources are eventually exhausted [16,20]. As in many other flotation processes, when the feed grade does not significantly change in gold-antimony flotation, working conditions are relatively stable and the ...

Antimony ore samples (mean assay 187 per cent antimony) from Endeavour Inlet, Marlborough Sounds New Zealand, were tested for upgrading by flotation to a saleable product (60 per cent antimony).The effects of activating agents, collectors, frothers, pH, conditioning time, and particle size on the recovery and grade of a stibnite flotation …
The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the …
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
Antimony leaching from tetrahedrite-bearing ores was typically carried out by using Na2S-NaOH solutions.

However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80. Additionally, the flotation plant residence time will often be determined solely by the grinding circuit capacity and feed slurry density. In the case of SAG mill – ball mill circuits, the fluctuations in
Sometimes, even if it can not directly select qualified antimony concentrate, it is often selected as a pre-selection operation for antimony flotation operations. Especially when flotation has many difficulties in processing antimony oxide ore at this stage, gravity separation is the main beneficiation method for antimony oxide ore.
