Problems solved by technology

[0002] Antimony, gold and arsenic symbiotic ores are complex ores that are difficult to process worldwide. Due to the limitation of smelting technology, pyrometallurgical smelting is generally adopted in China. When smelting gold and antimony concentrates with high arsenic content in raw materials, a large amount of arsenic is produced. Alkali slag has a huge impact on health and envi

Embodiment 1

[0022] Such as figure 1 As shown, the method for separating the antimony-gold-arsenic symbiotic ore of the present embodiment comprises the following steps:

[0023] S1 prepares a certain weight of antimony-gold-arsenic symbiotic ore; S2 adds the following agents to the antimony-gold-arsenic symbiotic ore according to the following proportion: 1.5kg / t Na 2 S, 2.5 kg / t Na 2 CO 3 , 120 g / t CuSO 4 , 120 g / tMA -2 and 15 g / t 2 # Oil; S3 continues to add the following agents to the antimony-gold-arsenic symbiotic ore at the following proportion and separate the antimony concentrate: 0.3 kg / t Na 2 S, 0.5 kg / t Na 2 CO 3 , 20 g / t CuSO 4 and 20 g / t MA -2 ; S4 Continue to add the following agents to the antimony-gold-arsenic symbiotic ore according to the following proportion and separate the gold-arsenic concentrate: 0.5 kg / t Na 2 S and 0.75 kg / t Na 2 CO 3 .

[0024] After separating the gold-arsenic concentrate, it is possible to continue to add agents to the antimony-gold...

Embodiment 2

[0026] Such as figure 2 As shown, the separation method of antimony-gold-arsenic symbiotic ore in this embodiment continues the following steps for the separated gold-arsenic concentrate after completing the separation steps in Example 1:

[0027] S6 conducts primary selection on the separated gold-arsenic concentrate, and puts the primary-selected gold-arsenic concentrate into the second tank; S7 conducts the first beneficiation of the gold-arsenic concentrate in the second tank, and sweeps at the same time , and store the gold-arsenic concentrate in slot three; S8 separates the antimony concentrate from slot three; S9 conducts a second selection of gold-arsenic concentrate in slot two; The arsenic concentrate is beneficiated for the third time, and the gold arsenic concentrate after beneficiation is stored in the first tank; S11 separates the gold concentrate from the first tank.

[0028] After completing the next step, all can get back to the previous step to continue the...

Abstract

The invention relates to the field of metallic ore, particularly to a separating method for antimony-gold-arsenic paragenetic ore. The separating method comprises S1, preparing the antimony-gold-arsenic paragenetic ore of a certain weight; S2, adding 1.5kg/t of Na2S, 2.5kg/t of Na2CO3, 120g/t of CuSO4, 120g/t of MA-2 and 15g/t of 2# oil to the antimony-gold-arsenic paragenetic ore ; S3, adding 0.3kg/t of Na2S, 0.5kg/t of Na2CO3, 20g/t of CuSO4 and 20g/t of MA-2 to the antimony-gold-arsenic paragenetic ore continuously and separating antimony concentrate; S4, adding 0.5kg/t of Na2S and 0.75kg/t of Na2CO3 to the antimony-gold-arsenic paragenetic ore continuously and separating gold-arsenic ore. According to the separating method, the antimony-arsenic separating process through a sodium carbonate-sodium sulfide method is adopted, selective flotation of arsenic is achieved at the utmost through antimony suppression and arsenic flotation, the recovery rate of arsenic in gold-arsenic concentrate is improved, and the content of arsenic in the antimony concentrate is reduced.

Description

technical field [0001] The invention relates to the field of separation of metal ores, in particular to a method for separating antimony, gold and arsenic symbiotic ores. Background technique [0002] Antimony, gold and arsenic symbiotic ores are complex ores that are difficult to process worldwide. Due to the limitation of smelting technology, pyrometallurgical smelting is generally adopted in China. When smelting gold and antimony concentrates with high arsenic content in raw materials, a large amount of arsenic is produced. Alkali slag has a huge impact on health and environmental protection. In addition, there is another kind of hydrometallurgy technology, but the industrial application of hydrometallurgy technology is not yet mature in China, and the cost is relatively high. Since the separation of antimony and arsenic is a worldwide problem, although domestic and foreign beneficiation scholars have done some research on it, no breakthrough has been made. If the antim...
