If it moves in water even like a sloth try some jet dry that breaks the tension of the water, the gold being heavy drops out to the bottom of the pan. You can wash the lighter weight material out and concentrate on the good stuff. I'm Assuming you know that but haven't seen a picture of the refined concentrats.

Declining ore grades and increasing mineralogical complexity of the South African platinum group mineral (PGM) ores have prompted the industry to investigate novel collectors that could outperform thiol collectors. One such example is Tecflote TM, a family of patented nitrile-based collectors for sulfide flotation by Nouryon, Sweden …
The West Qinling orogen in central China is an important gold prospective area, containing a series of large gold deposits, e.g., Baguamiao, Yangshan, Liba, Ma'anqiao, Pangjiahe, and Xiajiadian gold deposits (Ding et al., 2021).Currently, more than 100 sediment-hosted gold deposits with an estimated gold resource of over 2, 000 tons, …
Application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation …
Under optimized conditions, roasting carbonaceous gold ore with 10 wt% NaCl at 800 ℃ yielded to 92.05% gold, 92.56% zinc and ＜5% iron volatilization, respectively.
Using Kerosene as an Auxiliary Collector to Recover Gold from Refractory Gold Ore Based on Mineralogical Characteristics. Xuesong Sun 1,2, Jianwen Yu 1,2,*, …
Six different collector conditions including collectorless flotation were measured at a natural ore pH of 7.3. This ore has primarily free gold species, a very small amount of gold associated with pyrite, and 5.6% by weight of the ore is pyrite.
Promoters or Collectors. The commonly used promoters or collectors are "Aerofloat" reagents and the xanthates. The most effective promoter of free gold is Aerofloat flotation reagent 208. When auriferous pyrite is present, this reagent and reagent 301 constitute the most effective … See more

Section snippets Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig …
Five main classes of collectors are used in iron ore flotation: (Fig. 2) On the basis of selective removal of iron oxide and gangue, direct flotation (in which iron minerals are floated) and ...
