This type of process for metal sulfide ore containing arsenic and carbon, quartz clastic rock type gold ore, the ore sulfides are mainly of pyrite, arsenopyrite, metal oxides are mainly magnetite, limonite, Huang Jiatie Ba, a small amount of scorodite, in addition to see natural gold, non metallic minerals are mainly a small amount of quartz, mica, graphite, metal mineral content as shown in table 1.
The ore mineral dissemination size is very small, with irregular granular scattered, few in veinlet stockwork or distribution, and form part of mineral metasomatic structure. The size of uneven thickness. Such as limonite general distribution between 0.074~0.037 mm, 0.037 mm less than the vast majority of arsenopyrite particles. The general distribution of magnetite pyrite, 0.074~0.037 mm, yellow potassium iron barium was mostly below 0.053 mm.
Embedded complex natural gold, pyrite, arsenopyrite and gangue, the intercalation is closely related with the times, limonite, and according to their different parts can be divided into gold, intergranular gold and fissure gold, of which the former two, a small amount of the latter. The relative content of dissemination of natural gold in table 3.
Exploration on various types of flotation condition and medicament, chose the reasonable flotation engineering conditions for small closed-circuit test, following the closed-circuit test:
The gold ore grade of 7.31 grams / ton, concentrate grade of 55.62 grams / ton, tailings grade of 2.67 g / T, the gold recovery rate of 67.11%.
