  • Enhanced flotation of refractory gold ore by using sulfur

    1/7/2016· In order to test the effect of emulsified kerosene, experiments were conducted in this section based on Section 4.2.1. A mass of (NH 4) 2 S 2 O 3 (2.325 g) was mixed with 30 mL water and then the gold powder (0.32 g) was added. pH value of the solution was regulated to 4 by sulfuric acid.

  • The flotation of gold bearing ores — A review ScienceDirect

    1/7/1994· The practice of the flotation of pure gold and gold-bearing ores such as tellurides, aurostibite, kerogen, pyrite, pyrrhotite, copper-gold ores and mixed sulphides is reviewed. The factors which influence the choice of collectors, pH and Eh, are discussed as well as the application of differential flotation.

    This is usually done by flotation of arsenopyrite, pyrite, or other gold-bearing sulfides. To be economically justifiable, preconcentration should meet two objectives. First, the gold recovery to the concentrate should be sufficiently high that the tailings can be discarded without further treatment, and the mass ratio of concentrate to tailings should be low.

  • Gold extraction Wikipedia

    Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.[1] Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

  • Questions About Gold Flotation Processing Technology

    Gold flotation method is the main processing method for gold-bearing sulfide ores. The main characteristics of this kind of ores are often gold, silver, lead, sulfur and other minerals. Metal minerals include pyrite, sphalerite, galena, chalcopyrite, etc. Gangue minerals are mainly quartz, and include calcite, barite and other minerals.

    At good operating conditions, the floc flotation of galena and sphalerite fines can reach floatabiliJy of 100%, in comparison to conventional flotation obtaining floatability of about 40%. It has been found that a small addition of kerosene greatly improved the floc flotation, saving a large amount of PAX.
