Abstract
The invention discloses a regrinding and rescreening method and device of gold floating tailings, and belongs to the technical field of gold mineral separation. The method comprises the following steps that the floating tailings are graded and then enter a tailing filter pressing system in an overflowing mode, a filter cake enters a tailing pond, and tailing water is recycled; cinnabarite enters a mill to be reground, the mill performs discharging, the cinnabarite returns to the mill to be reground after graded, and the cinnabarite flows over to enter the mill to be floated; after one-time ore grinding, a hydrocyclone performs grading, the cinnabarite returns to be reground, and enters the hydrocyclone to be graded in an overflowing mode, and the cinnabarite enters a second-segment mill and flows over to be floated; the index with the gold concentrate grade of 12g/t and the recycling rate of 45 percent can be achieved.
Description
Technical field
The present invention relates to gold ore technical field, particularly relate to a kind of golden flotation tailing regrinding and reconcentration method and device thereof.
Background technology
Flotation is suitable for process particulate and fine granule material, is difficult to reclaim the fine mineral particle being less than 10 μm, also can uses floatation process by other beneficiation methods.The flotation technology of some special disposal superfine particles, callable granularity lower limit is lower, and ultra-fine flotation and ion flotation technology can reclaim from colloidal solid to all kinds of materials being molecule, ionic condition.Flotation also can sort the intermediate products of pyrometallurgy, the useful component in volatile matter and slag, and the precipitated product of process hydrometallurgy leached mud and displacement reclaims the inorganic matter in chemical products and waste water and organic matter.
A lot of to the recovery method of golden flotation tailing at present, but limitation is all very large, can only for certain class particular ore, some is the noble metal extracted again wherein, and some extracts that some are nonmetal, or directly as construction material, it is high all to there is cost in these methods, is difficult to the difficult problem promoted.
Summary of the invention
The invention provides a kind of golden flotation tailing regrinding and reconcentration method and device thereof.
The present invention adopts following technical scheme:
The concrete steps of golden flotation tailing regrinding and reconcentration method of the present invention are as follows:
