Method for improving the extraction yield of Silver and gold in Minerals of Gossan

摘要

Procedure to improve the performance of extraction of Gold and Silver in ores gossan.consiste in putting in contact with an Alkaline solution of SODIUM SULFIDE to the emperature Environment the Gossan of head or Tail of the Gossan already Treaty to which you want to extract the residual Silver It still contains.The contact with this solution with the Alkaline Sulphide mineral in any degree of Division can be performed in various ways, as in a Stirred Tank reactor or a reactor type in Pachuca with Passage of an Inert Gas (non oxidizing) or not, and to shake the Pulp, in any IER or practicing in the leaching reactor column in which the bed is the mineralThickening or preferably through leaching in situ, or in a pool, terrace or on the same floor, that is how to obtain the best results.
