What Can I Do For You?
Ion exchange resins, that are semi-selective for gold, have been extensively used for gold recovery from cyanide leach processes in the former ussr.Despite forward looking statements by researchers and technology vendors, there have been very few applications in western plants.Get Price

In these days, technology is running very fast.And we replace our old electronics with new and latest technology version.Especially, cell phone and computer replace quickly.But, did you thought that if you save all these old electronic devices and make gold with them.Friends in this blog you will learn that how to make gold with e waste.Get Price
Due to treatment of refractory carbonaceous low-grade gold ores a new technology providing improved precious metal recovery is required.For this reason, a technology including gravity, flotation, recleaning of the flotation concentrate, intensive cyanidation of the gravity concentrate and carbon in leach cil-process for intensive cyanidation tailings and the recleaned concentrate was developed.Get Price

The technology was developed over 20 years of research and around 10 million in investment, culminating in its first gold pour last year.This process replaces cyanide with a reagent, known as thiosulphate, creating a relatively cost-effective and non-toxic alternative to conventional cyanide- and mercury-based recovery process.Get Price
And a series of parameters, such as oxidants selection, the iodineiodide ratio, solid-to-liquid ratio, acidity ph and leaching time, affect the gold leaching efficiency.Through a comparison with several other hydrometallurgical processes, the presenting merits promote iodine-iodide system to be a promising method for gold recovery.Get Price
An overview of the enviroleach gold recovery process agents have been identified that improve the gold leach kinetics as well as the stability of the gold that has leached into solution.These leach modifying additives are a unique and key component in the effectiveness of this process.Get Price
Gold recovery from sand and rocks is also known as gold mining.Gold mining is a very profitable business.But cant do every body.Because you will need a large investment and heavy machinery.And one thing more a government permission.But, conditions are different for gold recovery from e-waste.You can also call this e-waste recycling.Get Price
The at gold features advanced, proportional pro audio modes.This allows the user to hear subtle changes in a targets response.Proportional audio also helps the user to better judge a targets size, shape and depth and has the additional benefit of a much faster recovery time when detecting adjacent targets.Get Price
