Collecting agent for floating cupric sulfide ore

Abstract

The collecting agent for floatation of copper sulfide ore is prepared by using thionocarbamate, diethylthionitrogen ester, 730A, dialkyl phosphorodithioate and propenyl butyl sulfonate according to the ratio of 0.6-0:0-0.06:0.2-0.1:0.1: 0.1-0.2, and its preparation method includes the following steps: respectively filtering thionocarbamate and 730A; under the condition of normal temp. and normal pressure slowly adding diethylthionitrogen ester while stirring, uniformly stirring them, then adding it and propenyl butyl sulfonate into dialkyl phosphorodithioate, stirring for 1 hr. then standing still for 2 hr. and removing precipitate so as to obtain the invented collecting agent with good selectivity and strong collecting power, and it can effectively separate copper-sulfur, copper-in and copper-arsenic, etc.

Description

Technical field:

[0001] The invention relates to a chemical agent technology for mineral processing in the nonferrous metal industry, in particular to a collector for flotation copper sulfide ore. Background technique:

[0002] At present, most of the collectors used in the flotation of single sulfide ore or polymetallic copper sulfide ores are xanths, the foaming agent is terpineol oil, and the regulator is mostly lime, commonly known as the "old three". With the development of the metallurgical industry, the number of easy-to-select ores gradually decreases, and the status of complex and difficult-to-select ores becomes more and more prominent. For this type of ore, the "old three" have become less and less suitable for the requirements of the flotation industry. In recent years, some agents or compound agents have been researched and developed one after another. Compared with the "old three", these collectors have certain application effects in production practice, but o...
