Using a solution of what is essentially reusable table vinegar the team has shown that for CAD$66 about US$47 it can produce one kilogram 2.2 lb of gold with 100 liters 26 gal of reusable
95% recovery of gold from a leaching solution step one oxidative sulfuric acid; step two thiourea leach; step three recovery of gold with activated carbon in their proposed method 9 . Kogan et al succeeded in extracting 98% gold from a leaching solution using a solvent extraction method 10 . In the process presented by Biong et al over

Concentrated Vinegar Technology 27-02-2016 10:57 AM. Stephen Foley is looking to get his hands on some gold… the problem is that it takes too much time costs too much money and harms the environment. What Foley and his research team discovered is a process that extracts gold efficiently and effectively without any of the downfalls of
What Foley and his research team discovered is a process that extracts gold efficiently and effectively without any of the downfalls of current industry practices. “We use one of the most mass-produced chemicals: acetic acid; at five per cent concentration it’s plain table vinegar.
Less dangerous way of refining gold
Concentrated Vinegar Technology The second process is precipitation of the gold with a reducing agent. There are many to choose between. This new leaching method is highly promising to find industrial appli ions for recovery of palladium from both primary and secondary sources likePGM ores spent alysts copper anode slime and
Hillbilly Labs: We use extreme agitation to keep the medium in constant motion increasing surface area for acid and oxidizer to work more efficiently and..
Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price but in the current gold price and cost environment a good rule of thumb is that a minimum GSR of
