Problems solved by technology

However, there are still some deficiencies in these technological methods: for complex and refractory copper oxide ores, the product index is not ideal; wet leaching treatment of copper oxide ores consumes a large amount of leaching agent, takes a long time to process, and has high leaching costs. High ore, the effect is not obvious; segregation-flotation combined process treatment process, the process is long and the operation is complicated

Embodiment 1

[0048] use figure 1 The process flow shown is to carry out flotation treatment on a copper oxide mine in Yunnan, as follows.

[0049]The copper oxide ore sample was taken from a copper oxide mine in Yunnan. The raw ore contained 1.5% copper, and copper existed as free copper oxide and bound copper oxide, of which bound copper oxide accounted for 8.6%. The mineral is ball milled by adding 500g / t water glass in advance to obtain a floatable slurry with a monomer dissociation degree greater than 90%;

[0050] Floatable pulp has undergone 2 times of roughing, 2 times of sweeping and 4 times of beneficiation:

[0051] Rough selection 1. Add 400g / t of ammonium sulfide, 300g / t of α-hydroxyphenylpropenylphosphonous acid and 150g / t of hexyl xanthate,

[0052] Add 300g / t of ammonium sulfide, 200g / t of α-hydroxyphenylpropenyl phosphonous acid and 100g / t of hexyl xanthate to roughing two;

Embodiment 2

[0062] use figure 1 The process flow shown is to carry out flotation treatment on a copper oxide mine in Xinjiang, as follows.

[0063] The copper oxide ore sample was taken from a copper oxide mine in Xinjiang. The raw ore contained 2.11% copper, and copper existed as free copper oxide and bound copper oxide, of which bound copper oxide accounted for 5.8%. The mineral is ball milled by adding 750g / t water glass in advance to obtain a floatable slurry with a monomer dissociation degree greater than 90%;

[0064] Floatable pulp has undergone 2 times of roughing, 2 times of sweeping and 4 times of beneficiation:

[0065] Rough selection 1. Add 400g / t of ammonium sulfide, 250g / t of α-hydroxy-2-methyl-3-phenylpropenylphosphonous acid and 250g / t of butyl xanthate,

[0066] Add 300g / t of ammonium sulfide, 200g / t of α-hydroxy-2-methyl-3-phenylpropenylphosphonous acid and 200g / t of butyl xanthate in roughing two;

[0067] Add 100g / t of ammonium sulfide, 100g / t of α-hydroxy-2-methyl...

Embodiment 3

[0076] use figure 1 The process flow shown is to carry out flotation treatment on a copper oxide mine in Hubei, as follows.

[0077] The copper oxide ore sample was taken from a copper oxide mine in Hubei. The raw ore contained 0.65% copper, and copper existed as free copper oxide and bound copper oxide, of which bound copper oxide accounted for 10.8%. The mineral is ball milled by adding 1000g / t water glass in advance to obtain a floatable slurry with a monomer dissociation degree greater than 90%;

[0078] Floatable pulp has undergone 2 times of roughing, 2 times of sweeping and 4 times of beneficiation:

[0079] After roughing, add 400g / t of ammonium sulfide, 300g / t of ethyl xanthate and 300g / t of α-hydroxy-2-ethyl-3-phenylpropenylphosphonous acid,

Abstract

The invention relates to the technical field of mineral processing, and specifically discloses a flotation method for copper oxide ore. The flotation method of copper oxide ore is to mix the original ore of copper oxide ore with inhibitor, and then grind the ore to obtain a floatable pulp; and 2 times of scavenging, and then 4 times of beneficiation, the ore in each operation returns to the previous operation in sequence, and finally flotation to obtain copper oxide concentrate products, in which the collectors used are α-hydroxyarylphosphonous acid and alkyl Mixed collectors for xanthates. The copper oxide ore flotation method provided by the invention simplifies the treatment process of the copper oxide ore, and improves the grade and recovery rate of the obtained copper oxide concentrate product.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to the technical field of ore dressing, and specifically discloses a flotation method for copper oxide ore. Background technique [0002] Copper oxide ore is an important part of the world's copper resources, and its reserves are relatively abundant. Oxidation zones are widely distributed in the upper part of most copper sulfide deposits, and some sulfide deposits have evolved into large and medium-sized sulfide oxide deposits due to long-term oxidation. As the copper sulfide ore is gradually exhausted, the treatment of copper oxide ore becomes more and more important. Therefore, the development and treatment of sulfide copper oxide ore is of great significance to the development of copper metallurgy industry. [0003] The composition of copper oxide ore is relatively complex, the structure is loose and brittle, the hydration is also strong, and it contains a large amou...
