Problems solved by technology

[0010] From the point of view of the existing tungsten-associated sulfide ore recovery process, the rough concentrate is basically obtained through shaking table or / and jigging. There are few reports on recovering valuable metals from shaking table or / and jigging coarse concentrate by flotation

Embodiment 1

[0031]The ore feed is tungsten ore associated with sulfide ore in a certain place in northern Guangdong. The associated sulfide ore is mainly copper, bismuth, sulfur, etc. After obtaining tungsten coarse concentrate containing sulfide ore through jigging and shaking table, the sulfide-containing Grind the tungsten coarse concentrate of the ore until the particle size is -0.074mm, accounting for 79%, add water to the slurry concentration of 35%, add quicklime to adjust the pH to 12; add collector Z-200 150g / t, stir for 2 minutes, and make coarse Sweeping, to obtain roughing copper concentrate and roughing copper tailings; add collector Z-200 40g / t to the roughing copper tailings, stir for 3 minutes, do sweeping, get sweeping copper concentrate and sweeping copper Tailings; Sweep copper concentrate and return to copper roughing operation; add inhibitor quicklime 1000g / t to rough copper concentrate, adjust pH to 12, stir for 3 minutes, add collector Z-20020g / t, Stir for 2 minutes...

Embodiment 2

[0035] The ore supply is tungsten ore associated with sulfide ore in a certain place in Jiangxi. The associated sulfide ore is mainly copper, bismuth, sulfur, etc. After obtaining tungsten rough concentrate containing sulfide ore through jigging, the tungsten rough concentrate containing sulfide ore Grind the ore until the particle size is -0.074mm, accounting for 85%, add water until the slurry concentration is 33%, add quicklime to adjust the pH to 12.5; add collector Z-200 130g / t, stir for 2 minutes, and do roughing to obtain Rough separation of copper concentrate and rough separation of copper tailings; add collector Z-200 30g / t to the rough separation of copper tailings, stir for 3 minutes, and do scavenging to obtain scavenging copper concentrates and scavenging copper tailings Sweep copper concentrate and return to copper roughing operation; add inhibitor quicklime 800g / t to rough copper concentrate, adjust slurry pH to 11, stir for 3 minutes, add collector Z-200 30g / t, ...

Abstract

The invention discloses a method for recovering valuable metal from a sulfide ore-contained tungsten rough concentrate. The method is characterized by comprising the following steps: after an ore is grinded, water is added to mix slurry; quicklime is added to stir; the pH is adjusted; a capturing agent is added for roughing, scavenging and selecting to obtain a copper concentrate; a scavenged copper tailing is added with an adjusting agent, an activating agent and a capturing agent for roughing, scavenging and selecting to obtain a bismuth concentrate; a scavenged bismuth tailing is added with an activating agent and a capturing agent for roughing, scavenging and selecting to obtain a sulfur concentrate; and a scavenged sulfur tailing is reselected by a shaker to obtain a tungsten concentrate. The obtained copper concentrate has the copper grade of 17-26% and the recovery rate of 85-93%; the bismuth concentrate has the bismuth grade of 16-23% and the recovery rate of 83-91%; the sulfur concentrate has the sulfur grade of 38-46% and the recovery rate of 68-78%; and the tungsten concentrate has the tungsten grade of 52-62% and the recovery rate of 87-95%. The valuable metal recovery method, provided by the invention, is excellent in separation effect, high in recovery rate and low in sulfur content in the tungsten concentrate, and is suitable for recovering the valuable metal from the sulfide ore-contained tungsten rough concentrate.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and relates to a method for recovering valuable metals from tungsten rough concentrates containing sulfide ores through a combined process of preferential flotation-gravity separation, in particular to a method for recovering valuable metals from tungsten rough concentrates containing sulfide ores. A method for recovering valuable metals from tungsten ores. technical background [0002] With the continuous depletion of single rich ore resources in our country, poor, fine and miscellaneous ores have become the theme of mining today, and comprehensive recovery of valuable elements is an effective measure to maximize the recovery of poor, fine and miscellaneous mineral resources. Although the content of associated sulfide ores in ore deposits is relatively low, they account for a high share of valuable metal production in my country. Therefore, the recovery of associated minerals can not...
