Problems solved by technology

And with the continuous development and utilization of gold, gold resources are gradually decreasing, and most of the existing gold resources are small, barren or have many impurities, so the difficulty of processing the existing gold resources is also increasing. In the prior art, methods such as roasting plus flotation, hot-pressed oxidation plus leaching, chlorination and oxidation leaching, carbon preference plus flotation, or carbon suppression plus flotation are often used to process these ores. There are problems such as complex process and high cost in the processing method, so there is an urgent need for a simple and low-cost process

Embodiment

[0041] like figure 1 As shown, the beneficiation process of a kind of high-carbon high-oxidation fine-grained gold ore provided by the embodiment of the present application comprises the following steps:

[0042] S1: Mix the raw ore with 1000 parts of sodium hydroxide and 2000 parts of sodium carbonate, pretreat it with a ball mill, and perform classification treatment to obtain pulp 1;

[0043] S2: adding composite higher alcohol, dispersant, and activator to pulp 1 for stirring treatment to obtain pulp 2;

[0044]S3: adding the pulp 2 to the collector for stirring treatment to obtain the flotation pulp;

[0045] S4: After stirring evenly, carry out roughing treatment to obtain rough tailings and rough concentrate;

[0046] S4-1: Concentrating the rough concentrate obtained from roughing;

[0047] S4-2: Sweeping the rough tailings obtained from roughing.

[0048] In some embodiments of the present invention, based on the idea of ​​simple, feasible and low-cost design, the...

Abstract

The invention provides a beneficiation process for high-carbon high-oxidation micro-fine particle gold ore, and relates to the technical field of ore beneficiation. The process comprises the following steps: mixing raw ore with 1000 parts of sodium hydroxide and 2000 parts of sodium carbonate, and conducting crushing by using a ball mill to obtain ore pulp 1; subjecting the ore pulp 1 to grading treatment, and returning coarse materials obtained through separation treatment for smashing treatment; carrying out stirring treatment on fine materials obtained through separation treatment; after uniform stirring, carrying out roughing treatment to obtain rough tailings and rough concentrates; carrying out concentration treatment on rough concentrate obtained by roughing; and conducting scavenging treatment on rough tailings obtained through roughing. The technological process is simple, the cost is low, the grade of the gold concentrate is improved, and the recovery rate of beneficiation is increased.

Description

technical field [0001] The invention relates to the technical field of ore beneficiation, in particular to a beneficiation process of high-carbon and high-oxidation fine-grained gold ore. Background technique [0002] As an extremely important strategic resource in the world, gold is the hard currency of the world. And with the continuous development and utilization of gold, gold resources are gradually decreasing, and most of the existing gold resources are small, barren or have many impurities, so the difficulty of processing the existing gold resources is also increasing. In the prior art, methods such as roasting plus flotation, hot-pressed oxidation plus leaching, chlorination and oxidation leaching, carbon preference plus flotation, or carbon suppression plus flotation are often used to process these ores. There are problems such as complex process and high cost in the processing method of the present invention, so a simple and easy and low-cost process is urgently ne...
