Embodiment 1

[0013] Without adding any chemicals, the antimony-gold mixed concentrate was naturally selected for separation test. The process is detailed in figure 1 . Put 500g of ore containing 4.8g / t gold and 0.52% antimony into the laboratory-type ore grinding machine, the size of the grinding machine is Φ200×240mm, the grinding concentration is 60%, the grinding time is 8 minutes, and the grinding fineness reaches - 43μm (-320 mesh) accounts for 90%, and the finely ground pulp is used in a laboratory-type flotation machine with a specification of 1.5 liters, and water glass 300g / t, lead nitrate 60+40g / t, ethylsulfide nitrogen 60+ 40g / t, pine oil 60+30g / t, roughing and sweeping for a total of 8 minutes to obtain antimony-gold mixed concentrate containing 11.25% antimony and 38g / t gold, which was carried out in a 0.5-liter flotation machine for 3 After the second refinement, 4.5g of antimony concentrate was obtained, the antimony grade was 41.33%, the recovery rate was 71.53%, the gold ...

Embodiment 2

[0015] Add bleaching powder 1000g / t to antimony-gold mixed concentrate to carry out conventional separation test, the process flow is detailed in figure 2 .

[0016] Put 500g of ore containing 4.8g / t gold and 0.52% antimony into the laboratory-type ore grinding machine, the size of the grinding machine is Φ200×240mm, the grinding concentration is 60%, the grinding time is 8 minutes, and the grinding fineness reaches - 43μm accounts for 90%. The finely ground pulp is used in a laboratory-type flotation machine with a specification of 1.5 liters, and 300g / t of water glass, 60+40g / t of lead nitrate, 60+40g / t of ethyl disulfide, pine Oil 60+30g / t, roughing and sweeping for 8 minutes to obtain antimony-gold mixed concentrate containing 11.25% antimony and 38g / t gold, concentrate once in 0.5 liter flotation machine and add 1000g of bleaching powder / t for 1 separation, the time is 8 minutes, 3.9g of antimony concentrate is obtained, the antimony grade is 39.45%, the recovery rate ...

Embodiment 3

[0018] Add 200g / t of trichloroisocyanuric acid proposed by the present invention in antimony-gold mixed concentrate and carry out separation test as ore dressing inhibitor, its technological process is detailed in figure 2 .

[0019] Put 500g of ore containing 4.8g / t gold and 0.52% antimony into the laboratory-type ore grinding machine, the size of the grinding machine is Φ200×240mm, the grinding concentration is 60%, the grinding time is 8 minutes, and the grinding fineness reaches - 43μm accounts for 90%. The finely ground pulp is used in a laboratory-type flotation machine with a specification of 1.5 liters, and 300g / t of water glass, 60+40g / t of lead nitrate, 60+40g / t of ethyl disulfide, pine Oil 60+30g / t, roughing and sweeping for 8 minutes to obtain antimony-gold mixed concentrate containing 11.25% of antimony and 38g / t of gold, which is purified once in a 0.5-liter flotation machine and then added with trichloride Isocyanuric acid 200g / t was separated once for 8 minut...

Abstract

The invention advances an application of trichloroisocyanuric acid acting as a new ore-dressing inhibitor at 200-400g / t with respect to weight, trichloroisocyanuric acid is mainly used to sterilize and bleach, and it is for the first time that it acts as an inhibitor of arsenical pyrite and sulfurous iron ore, as a new ore-dressing inhibitor, it plays a remarkable role in separating white antimony from arsenical pyrite and from sulfurous iron ore, showing a stronger inhibition of arsenical pyrite and sulfurous iron ore but has no bad influence on the white antimony, good-selectivity, an effective inhibitor of arsenical pyrite and sulfurous iron ore.

Description

technical field [0001] The invention relates to a new application of trichloroisocyanuric acid, in particular to the application of trichloroisocyanuric acid as a novel ore dressing inhibitor in the field of mining and metallurgy. Background technique [0002] Trichloroisocyanuric acid, TCCA for short, molecular formula C 3 N 3 o 3 CI 3 , Molecular weight 232.44, also known as strong chlorine essence. Its products are white powder, or dosage forms such as granules, flakes, and sticks. They have the pungent odor of hypochlorous acid and will decompose when heated or in contact with a small amount of water. Trichloroisocyanuric acid is a strong oxidant, and it will react strongly with flammable organic substances, acids, alkalis, and ammonia-containing compounds. [0003] Trichloroisocyanuric acid is an efficient and broad-spectrum organochlorine disinfectant and bleach that can kill various bacteria, algae, fungi and viruses. Because the final products of its hydrolysis...
