how in the world do i get g out of that rock? over the s, people have come up with some ingenious ways to extract g from ore, or the solid substance (like rocks or minerals) that contain valuable metals or minerals. people can crush the rocks, heat the rocks and even treat the rocks with chemicals. this lesson will explore the third option, focusing on how sodium cyanide is used to remove g from ore in a process called g cyanidation, or when cyanide is used to make g watersoluble. see full list on study if you 39;ve ever heard of cyanide, you probably know it can be deadly. historically, it has been used to kill people, whether that is in the german gas chambers used during world war ii, or the execution of people on death row in the united states. it kills by preventing cells from using oxygen, which eventually results in the death of tissues. and it is pretty toxic. a teaspoonsized amount containing just 2% cyanide will kill a human. but what is it? cyaniderefers to a group of chemicals that contain carbon and nitrogen and, in addition to its toxicity, it can easily bond (or attach) to valuable metals, like g. so how does a killing agent find its way into g extraction? since most ores only contain 0.001% g or silver (by mass), back in 1887 a clever human in scotland discovered that using dilute amounts of cyanide (in the form of sodium cyanide) can aid in the process of g extraction. starting in the 1970s, most largescale mines began to use sodium cyanide in this fashi see full list on study how does it work? the chemical reaction is pretty straight forward: you mix ore that contains g with sodium cyanide in the presence of oxygen and water and you get sodium g cyanide and sodium hydroxide. g does not dissolve in water, so the overarching goal of adding sodium cyanide to the ore, is to make g dissolvable (or soluble) in water. let 39;s discuss the steps involved: 1. the ore is crushed, and any g that is free, meaning it is not stuck in the ore, is removed. 2. in most cases, the ore is piled on top of a material that is only permeable to certain substances. 3. sodium cyanide is added to the ore. 4. as was mentioned earlier, when the sodium cyanide is added you get the watersoluble form: sodium g cyanide. 5. the water soluble sodium g cyanide can move through the material on the bottom of the heap where it is collected, whereas the rest of the ore is impermeable and does not go through the material. 6. lime is added as well to keep the materials basic ( see full list on study clearly there are some environmental risks to spraying a toxic chemical on rocks, and yet using cyanide allows miners to make a profit on lowgrade ores. the world 39;s demand for reasonably priced precious metals drives the need to use cyanide. let 39;s look at some of the issues with using cyanide. the process requires a deep pit, which tears up the land. but the main problem is when cyanide gets into places it shouldn 39;t. for example, in the 2000, 3.5 million cubic feet of cyanide leaked into the water in central europe, and eventually polluted 250 miles of rivers in yugoslavia and hungary. or in 1982, 52,000 gallons of cyanide leaked into the water supply of a town in montana, and the city had to find a new water source. and in another catastrophe, in 1980 an earthquake in japan caused cyanide to leak into a waterway and resulted in the death of all organisms living in the stream. see full list on study cyanide g processing tanks for saleg leaching processing for sale . cyanide g processing tanks for sale. doc vat leaching and elution plant g traditional vat leaching is a batch process however with materials handling being of high vats are tanks built by bricks cement and sand may be rectangular or into solution dissolution by reaction of g present into tails and home agra global leader in the manufacture and supply of sodium cyanide australian g reagents (agr) deliver quality sodium cyanide to your mining operations with endtoend expert support from an experienced western australian team.
