pretreatment of refractory gold ore with microwaves

pretreatment of refractory gold ore with microwaves. Microwave pretreatment of a double refractory gold Abstract Double refractory gold ores, such as Barrick's Goldstrike ore, contain both pyrite and carbonaceous matter and the latter results in the loss of gold from solution during cyanide leaching One possible remedy is to roast the ore and thus oxidize the pyrite and

Microwave-assisted leaching—a review ScienceDirect

2004-6-1  Hydrometallurgical extraction of gold from its ores by leaching with sodium cyanide proceeds according to the following reaction (Habashi, 1970): (12) 4 Au +8 NaCN + O 2 +2 H 2 O →4 NaAu (CN) 2 +4 NaOH. However, gold recovery from refractory gold ore is very low when conventional cyanide leaching is applied without pre-treatment.

Is There Gold Worth Scrapping in Household Appliances

2020-11-11  Gold-bearing circuit boards are increasingly used in appliances like microwaves, air conditioners, refrigerators, and kitchen stoves. A good rule of thumb is: The more technological features that an appliance has, the more likely it is to contain small amounts of gold. Another component to look for in your appliance if you want to extract

Can I Microwave a Bowl With Gold Trim? Hunker

2020-4-1  Generally, it is not safe to put gold trimmed bowls in your microwave. Microwaves are super convenient modern appliances — until you hear some sparks, smell some smoke and realize that a mini-disaster has occurred in your kitchen after putting your gold-trimmed china inside the machine. It's easy to make this mistake, especially when the trim

The gold concentrate was pretreated using microwaves with different irradiation time. The sample temperature was increased up to 950 °C by the microwave irradiation.

Microwave heating processes involving carbon materials

2010-1-1  Carbon materials are, in general, very good absorbents of microwaves, i.e., they are easily heated by microwave radiation. This characteristic allows them to be transformed by microwave heating, giving rise to new carbons with tailored properties, to be used as microwave receptors, in order to heat other materials indirectly, or to act as a catalyst and microwave

Checklist of Old Electronic Devices that Contain Gold

2017-5-26  Old laptops and desktops Big old desktop computers are about as useful as doorstops, but they still contain small quantities of gold. Pile them up, call us up, and we can explain how to recycle them profitably. And don’t forget that gold can be found on printed circuit boards, modem cards, graphics cards, memory chips and other extras that got stuffed into
