Embodiment 1

[0052] The method for desulfurizing and recovering the sulfur-containing vanadium ilmenite concentrate of embodiment 1 and recovering the sulfur-cobalt concentrate comprises the following steps:

[0053] (1) The sulfur-containing vanadium ilmenite concentrate is prepared into slurry, specifically, the sulfur-containing vanadium ilmenite concentrate is mixed with water to prepare a slurry with a solid content of 25wt%.

[0054] (2) The first rougher flotation is performed on the pulp in step (1) to obtain the first rougher flotation concentrate and the first rougher flotation tailings.

[0055] Wherein, using sulfuric acid as the pH adjuster, the pH value of the pulp is adjusted to 4.5; using xanthate and butylammonium black medicine with a weight ratio of 4:1 as the collector, and the consumption of xanthate and butylammonium black medicine is 300g / t; 2# oil is a foaming agent, and its dosage is 60g / t.

[0056] (3) Perform first sweep flotation on the first rougher flotation...

Embodiment 2

[0071] The method of embodiment 2 is the same as that of embodiment 1, and its difference is only:

[0072] (1) mixing the sulfur-containing vanadium ilmenite concentrate with water to prepare a slurry with a solid content of 25wt%;

[0073] (2) when carrying out the first roughing flotation, adjust the pH value of the pulp to 4; adopt the xanthate and butylammonium black medicine with a weight ratio of 10:1 as the collector, and the consumption of the xanthate and the butylammonium black medicine is 100g / t; 2# oil is a foaming agent, and its dosage is 60g / t;

[0074] (3) During the first sweep flotation, the pH value of the first rougher flotation tailings pulp was adjusted to 4; xanthate and butylammonium black medicine with a weight ratio of 10:1 were used as collectors, and the yellow The dosage of medicine and butylammonium black medicine is 50g / t; 2# oil is a foaming agent, and its dosage is 30g / t;

[0075] (4) Nano-ceramic balls are used as grinding media, and the dia...

Embodiment 3

[0082] The method of embodiment 3 is the same as that of embodiment 1, and its difference is only:

[0083] (1) mixing the sulfur-containing vanadium ilmenite concentrate with water to prepare a slurry with a solid content of 60wt%;

[0084] (2) when carrying out the first roughing flotation, adjust the pH value of the pulp to 6; adopt the xanthate and butylammonium black medicine with a weight ratio of 1:1 as the collector, and the consumption of the xanthate and the butylammonium black medicine 500g / t; 2# oil is a foaming agent, and its dosage is 80g / t;

[0085] (3) During the first sweep flotation, the pH value of the first rougher flotation tailings pulp was adjusted to 6; xanthate and butylammonium black medicine with a weight ratio of 1:1 were used as collectors, and the yellow The dosage of medicine and butylammonium black medicine is 250g / t; 2# oil is a foaming agent, and its dosage is 80g / t;

Abstract

The invention discloses a method for desulfurizing and recovering sulfur-containing vanadium ilmenite concentrate and recovering sulfur-cobalt concentrate, comprising the following steps: preparing sulfur-containing vanadium ilmenite concentrate into ore slurry; performing first roughing flotation on the ore slurry to obtain The first rougher flotation concentrate and the first rougher flotation tailings; the first rougher flotation tailings are subjected to the first sweep flotation to obtain the first sweep flotation concentrate and the first sweep flotation Selecting tailings; combining the first roughing flotation concentrate and the first sweeping flotation concentrate and grinding to obtain a grinding product; performing the second roughing flotation on the grinding product to obtain a second roughing Flotation concentrate and second rougher flotation tailings; select the second rougher flotation concentrate to obtain sulfur-cobalt concentrate and first medium ore. The method of the invention has the advantages of good comprehensive recovery effect of the sulfur-cobalt concentrate, high sulfur grade and high recovery rate in the sulfur-cobalt concentrate.

Description

technical field [0001] The invention relates to the field of mineral processing engineering, in particular to a method for desulfurizing and recovering sulfur-cobalt concentrate from sulfur-containing vanadium ilmenite concentrate. Background technique [0002] The reserves of titanium resources in the Panxi region of my country account for about one third of the reserves of titanium resources in my country. The Panxi region is an important base for the development and utilization of titanium resources in my country. In addition to iron, titanium and vanadium, the iron and titanium resources in Panxi also contain a large amount of sulfur and cobalt. The sulfur and cobalt resources in the Panzhihua area are partly in the form of sulfides such as pyrrhotite, which will be enriched in vanadium-titanium-iron concentrates during the separation of vanadium-titanium-magnetite. This kind of vanadium ilmenite concentrate containing sulfur and cobalt will produce SO during the sinter...
