Seeking advice: the basic methods for dehydrating fine gold ore with high moisture content. Thank you
Thread Content
The gold ore has a moisture content of over 20% and its particle size is very fine – 200 mesh or finer. How can I dehydrate it quickly and easily? I would appreciate guidance from those with more experience
-- Damn it, even those in biomedicine have come to mine. Fine particle size is not necessarily difficult; it mainly depends on the properties of the ore. --
High-arsenic, extremely under-sulfidized fully ionized gold ore
-- :L isn’t a mineralogist, after all. It’s a challenge to distinguish between the subject and predicate of this noun, as well as to ensure that all modifying elements are paired up. I’ll ask the teacher tomorrow. High arsenic content, I understand. Extremely unsulfured? Does that mean it’s an oxidized ore? Extremely under-vulcanized – does that mean a mixed ore of semi-vulcanized and semi-oxidized states? But what does “extremely” mean? Does \"ionic gold mine\" refer to a gold mine of the ionic adsorption type? . . . . . I’m torn! --
Since the testing of the ore showed a low copper content, this indicates incomplete sulfidation. As a result, it is not possible to reduce more gold ions in the ore; this causes much of the gold to be enclosed within or bound to arsenopyrite crystals, making it impossible to process it using conventional cyanidation methods
-- Perhaps it is necessary to mix it with sulfide ores for roasting in order to break open the encapsulation. --
I plan to use wet oxidation; therefore, I would like to ask for advice on how to remove water. I’m not sure which flocculant would be the best choice
-- It seems that the flocculant needs to be used in conjunction with a thickener. I’m not sure what the process ahead of you is like right now. If it is dehydration by the underflow of a thickener, it seems that a belt filter is used for washing, filtering, and dehydration before sending it to calcination. --
For better results, a vertical filter press can be used; it results in low moisture content in the product, but the investment required is high
The volume is too large – around 200 tons per day, which might be inconvenient... I plan to use coagulants to precipitate some of the water or employ other methods to remove part of it, and then mix lime and cement to create granules. I’ll conduct some tests in the next few days to see how effective this approach is
Reply to 10# Lianzi: It should be possible; it’s just that the production cost is high. You can look up relevant information
