New flowsheet for the treatment of complex sulfide ores using synthetic collectors was written by Belardi, G.;Alesse, V.;Marabini, A. M.. And the article was included in Minerals & Metallurgical Processing in 1995.COA of Formula: C8H7NOS This article mentions the following:
An alternative flowsheet was designed for the flotation treatment of a complex sulfide ore from the Sotiel Mine in Spain. The ore contains 0.71% Cu, 2.24% Pb and 5.63% Zn. Two specially developed synthetic collectors, methylmercapto-benzoxazole (MMBO) and 6n-propoxy-mercaptobenzo-thiazole (PMBT), were examined MMBO exerts a specific action on copper and zinc minerals after treatment with copper sulfate, and PMBT exerts a specific action on Pb minerals. Flotation operating variables (pH, frother type, frother quantity and feed particle size) were examined by means of rougher flotation tests to determine the optimum conditions for the new collectors. Once the optimum conditions were determined, a series of open flotation circuits were run on feeds of various particle sizes (obtained by different types of grinding). The objective was to obtain high-grade Cu and zn concentrates The results of the open-circuit tests demonstrated that a Cu concentrate grading from 18% to 23% Cu and a Zn concentrate grading from 40% to 48% Zn can be produced. In the experiment, the researchers used many compounds, for example, 6-Methyl-1,3-benzoxazole-2-thiol (cas: 23417-29-0COA of Formula: C8H7NOS).
6-Methyl-1,3-benzoxazole-2-thiol (cas: 23417-29-0) belongs to benzoxazole derivatives. Being a heterocyclic compound, benzoxazole finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Benzoxazoles are prominent in medicinal chemistry due to their wide spectrum of pharmacological activities such as anti-inflammatory, antimycobacterial, antihistamine.COA of Formula: C8H7NOS
