Embodiment 1

[0039] Embodiment 1 prepares gold tailings particle

[0040] A kind of processing method of gold tailings of the present invention, comprises the steps:

[0041] (1) Take the gold tailings, pass through a 800-1250 mesh sieve after multiple screenings, and add a magnetic separator to screen out the fine iron ore, so that the iron ore content in the remaining tailings is lower than 0.5wt%;

[0042] (2) Add water to the remaining tailings to make tailings slurry, the amount of water added is twice the amount of tailings; then adjust the pH of the tailings slurry with dilute HCL solution or dilute NaOH solution according to the pH value of the tailings slurry Value to neutral, spare;

[0043] (3) adding talcum powder accounting for 2wt% of the tailings solids to the above tailings slurry for modification;

[0044] (4) Add a coupling agent (calcium carbonate and titanate coupling agent TMC-201 mixed at 1:1) accounting for 5wt% of the tailings solids to the tailings slurry after t...

Abstract

The invention belongs to the technical field of gold tailing recycling and reuse, in particular relates to a building plate with gold tailing granules, and further discloses a making method of the building plate. The building plate is made of gold tailing granules together with red mud and kaolin as raw materials, and the gold tailing granules are made of conventional gold tailing wastes as a rawmaterial by using a special treatment process. The building plate has the advantages of being light in weight and rich in pore, the pressure resistance strength of the building plate meets national standards, meanwhile, the obtained plate is excellent in fireproof property, and a novel way is provided for utilization of gold tailings and red mud residues.

Description

technical field [0001] The invention belongs to the technical field of recovery and reuse of gold tailings, in particular relates to a building plate containing gold tailings particles, and further discloses a preparation method thereof. Background technique [0002] In the history of more than 5,000 years of civilization in my country, gold has been used for more than 4,000 years. Like Egypt, India, and ancient Rome, it has become one of the first countries in the world to use gold and other alloys. Gold ranks 79th in the periodic table of chemical elements, its atomic weight is 197, and its density is high (19.32g / cm 3 ) but lighter than platinum. The color of gold is golden yellow, and it has good ductility. 31.25g of pure gold can be hammered into a gold leaf with a thickness of 1 / 10,000th of a millimeter, which can cover 9m 2 area. The volatility of gold is small, and the volatile amount of melted gold is insignificant under normal circumstances. Gold has good elect...
