REVIEW OF SEQUENCE ASSAY SCHEMES FOR COPPER SPECIATION AND ITS USE IN GLYLEACH~(TM)

摘要

A general description of the GlyLeach~(TM) leaching technology will be given, with a broad view of results from a number of different ores. Advantages and disadvantages of the method are discussed.The classical method for simple copper mineral speciation via assay is presented and reviewed in detail. Problems between objective and subjective tests are reviewed, and the reason for them explained. There is a radical difference between a mineralogical assay and a sequence assay.A graphical chart useful for interpretation of the normal sequence assay is presented and its use discussed.A new sequence assay sub group is proposed to deal with arsenate and antimonides that are soluble is sodium sulphide.Lastly, examples from real data are examined and compared with the actual response of several oxide and sulphide ores to Cu extraction using both GlyLeach~(TM) and classical acid leaching.
