Abstract

The invention provides mineral flotation collectors, namely sulfur ammonia ester thiourea composite-group compounds. The structural formula of the collectors is as follows, wherein R1 represents C1 to C8 alkyl, acyl groups of which the general formula is R3-C(=O)- or ester groups of which the general formula is R40-C(=O)-; R3 and R4 in the structural formula represent C1 to C8 alkyl respectively;and R2 represents C2 to C9 alkylene. Due to a plurality of coordination atoms and coordination groups in collector molecules, the sulfur ammonia ester thiourea composite-group compounds serving as flotation collectors can enhance the flotation, separation and extraction of nonferrous metal ores and precious metal ores and improve flotation efficiency, metal recovery rate and other characteristics.

Description

technical field

[0001] The invention relates to a mineral flotation collector-thiocarbamate and thiourea complex base compound. Background technique

[0002] Flotation reagent is the key technology for the separation and extraction of valuable mineral components by flotation. As mineral resources become poorer, finer, and miscellaneous, the development of new high-efficiency flotation collectors plays an important role in the development and utilization of complex and refractory ores and in improving the comprehensive recovery rate of metals.

[0003] Xanthate is a common collector for sulfide ore flotation, which has strong collection capacity but lacks selectivity. Compared with xanthate, dialkylthiocarbamate (thiocarbamate) has better selectivity, which is beneficial to the comprehensive recovery of beneficial elements such as copper, lead, zinc, gold or silver in sulfide ores. For further improving the flotation performance of thiourethane collector, allyl thiourethane...
