Gold extraction Wikipedia
Gold extraction is the extraction of gold from dilute ores using a combination of chemical processes Gold mining produces about 3600 tons annually, and another 300 tons is produced from recycling Since the 20th century, gold has been principally extracted in a cyanide process by leaching the ore with cyanide solutionSafety – Hydrocarbon extraction equipment operates at low pressures not exceeding 150 lbs per square inch, which makes it a safe process versus other higherpressure techniques Efficiency and high yields – Hydrocarbon extraction has lower cycle times as compared to other types of extraction, which greater efficiency and higher yieldsHydrocarbon Extraction Equipment | Enquire + Buy | PDXGold
