In this paper, the optimal treatment of industrial waste consisting from xanthate and oxidation
product, i.e. diisobutyl and diethyl dixanthogenate, was developed for production of flotoreagents.
Waste dixanthogenate was generated during production and storage of flotation agents, i.e. potassium
isobutyl (KiBuX) and potassium ethyl xanthate (KEtX), respectively. The process of waste xanthate
treatment is based on the reaction of the nucleophilic heterolysis of the persulfide bond in the
diisobutyl dixanthogenates by alkylamines in presence of various oxidizing agents (sodium
hypochlorite, hydrogen peroxide, potassium persulfate) to produce N-alkyl-, N,N-dialkyl- and N cycloalkyl-O-isobutyl thiocarbamate selective flotoreagents. Also, analogous methodology was
applied for synthesis of N-alkyl and N,N-dialkyl-O-ethyl thiocarbamate from KetX using sodium
hypochlorite at laboratory and semi-industrial level. The developed method provides the
corresponding alkyl thiocarbam...ates in a high yield and purity. The flotation efficiency was analysed
using the obtained thiocarbamate on a real sample of minerals in laboratory and industrial
conditions.
