Problems solved by technology

Xanthate collectors mainly include ethyl, butyl and isopentyl xanthates, etc. black drugs mainly include butylammonium black drugs, 15# and 25# phenol black drugs, No. 208, etc., and ester agents mainly include Z- 200. Collectors such as the ones above cannot take into account the collection of copper and molybdenum well. Those with strong collection power are often not selective enough for pyrite and other magnesium-containing silicate minerals. The collection of some target minerals is weak, and the subsequent separation of copper and molybdenum often cannot separate higher-grade molybdenum concentrates, so the existing flotation reagents are not suitable for this type of ore, so the development is suitable for a high-sulfur It is of great significance to use high-efficiency flotation collectors for fine-grained and complex embedded copper-molybdenum ores that are easy to muddy

Abstract

The invention discloses high-efficiency flotation collecting agent for high-sulfur iron easily-argillized fine-grained complex embedded copper-molybdenum ore and a preparation method and application thereof. The efficient flotation collecting agent for the high-sulfur iron easily-argillized refined fine-grained complex embedded copper-molybdenum ore is prepared from, by weight, 15-25 parts of xanthate, 15-25 parts of thionocarbamate, 6-10 parts of tartaric acid, 23-35 parts of modified oil and 20-30 parts of surfactant. The collecting agent is small in agent dosage, high in flotation speed, stable and non-sticky in foam property, balanced in copper-molybdenum collecting property and high in adaptability to high-sulfur iron and silicate gangue prone to argillization, the hydrophobic property of micro-fine particle copper-molybdenum ore products can be aggregated, the loss of micro-fine particle copper-molybdenum in sulfur in the copper-sulfur separation process is effectively reduced, and compared with a traditional xanthate collecting agent, subsequent copper-molybdenum separation operation is facilitated, and the high molybdenum concentrate grade can be obtained.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and further belongs to the technical field of flotation agents for copper-molybdenum ore, and specifically relates to a high-sulfur iron, easy-to-sludge, fine-grained and complex embedded copper-molybdenum ore high-efficiency flotation collector and its preparation method and application . Background technique [0002] With the continuous mining of large-scale porphyry copper resources in various countries in the world, copper resources are facing poverty, and skarn-type copper deposits have been paid more and more attention by mineral processing workers. Minerals have a greater impact on flotation, and there are mostly fine-grained embedded structures. Generally speaking, high pyrite and clay minerals that are easy to muddy will also interfere with the beneficiation process of copper ore, especially when the copper ore contains molybdenum. , the nature of these complex symbiotic fine-grained...
