Gold Ore And Mineral Processing

Of all the methods of extracting gold amp processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation,cyanidation and gravity concentration. Tests that mirror each of these unitoperations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery methods.

    The nominal primary grind size was 50um P80. Potassium Amyl Xanthate PAX was used as the sulphide mineral collector in the rougher circuit. The rougher circuit pH was maintained at natural through eight minutes of rougher flotation. For Tests 69 to 76 a gravity separation stage, including cyanidation of the gravity concentrate was included. Ultra-fine grinding of the flotation rougher concentrates was employed for selected tests to understand leach extractions of the concentrates.

    The primary grind sizing, for Flowsheet 2, was a nominal 50um P80, two tests were conducted at a coarse crush size of 3.350mm P80 to assess heap leach amenability of the selected composites. Leaching tests were carried out at a sodium cyanide concentration of 1,000 ppm for 96 hours. The pH in the cyanidation circuit was maintained at 11.0.

    Silver recoveries were higher using the flotation flowsheet withsubsequent cyanidation of the flotation concentrates. Recoveriesvaried between 59 and 81 percent of the silver in the feed, with anaverage of about 69 percent. Whole-of-ore cyanidation extractedbetween 29 and 47 percent, for an average of about 38 percent.

    Developments In Mineral Processing Advances In Gold Ore

    In 1936 when data were being compiled for Cyanidation and Concentration of Gold and Silver Ores, considerable published information was available on milling costs in various parts of the world. At the present time, however, it is extremely difficult to obtain reliable figures on the cost of ore treatment owing to the fact that during a period of rising prices and wages the mine managements do not consider current cost data typical of normal operation and are unwilling to release them for publication.

    Another factor which applies particularly to the United States and Canada and which tends to make cost-per-ton figures unreliable is the disparity between the rated capacity of many of the mills and the actualtonnage being handled today. This is partly attributed to shortage ofunderground labor and partly to the fact that during the war period not only was maintenance heavier than normal but opportunities for improvements in technique were lacking.

    The total cost of producing an ounce of gold in Canada increased from 22.35 in 1939 to 32.07 in 1945, according to the report of the director of the Ontario Mining Association for 1945. This represents a 43.5 per cent increase. From various other data which are available, however, it appears that milling and treatment costs mining excluded have probably not risen on the average over about 30 per cent. The broken line in Fig. 97 indicates estimated present 1948 average cost on the basis of this 30 per cent rise.
