— In order to investigate the effect of particle size on the flotation performance in the separation of copper-gold-lead, froth products of various size fractions were collected as a function of flotation time. The optimum dosage of potassium dichromate (K 2 Cr 2 O 7) and sodium diethyldithiocarbamate (DDTC) were determined by flotation conditional …
— 1. Introduction. Many polymetallic sulfide ores contain copper and lead minerals. Generally, the most common treatment methods include: (1) Bulk copper/lead flotation followed by copper/lead separation; (2) Sequential copper/lead flotation [1], [2].The main difficulty with the differential separation of chalcopyrite from galena lies in the …
— ZJ 201 (modified starch) is a non-toxic, odorless, and biodegradable polymeric depressant, which selectively depressed galena in batch flotation tests while chalcopyrite was not significantly affected. In a plant trial, copper-lead separation was successful for the first time without using dichromate. Moreover, the plant process could …
— The copper lead mixed concentrate produced by a copper lead zinc ore concentrator in Qinghai contains Cu 1.96% and Pb 56.39%, but the particle size of galena in the mixed concentrate is fine. Using traditional copper lead flotation reagent, there are some problems such as poor separation effect and high mutual content of product metals. In …
— The bulk flotation of copper-lead sulfide ore in the first stage is easy because both chalcopyrite and galena have better natural floatability than other sulfide ores, and this is also an important reason for saving reagents. However, the difficulties of copper-lead mixed flotation are related to the separation of copper lead mixed concentrate.
— In order to obtain satisfactory separation results, cyanides are widely used in the selective flotation of copper/lead/zinc and copper/zinc ores as depressant for sphalerite, pyrite, and certain copper sulfides, and sodium dichromate (Na 2 Cr 2 O 7) is used to depress galena in copper/lead separation [3]. Dichromate and cyanide are the commonly ...
— In general terms, the most common treatment methods include (a) sequential copper/lead/zinc flotation, and (b) bulk copper/lead flotation followed by copper/lead separation and zinc flotation. Another method known to be used in industrial practice is bulk copper/lead/zinc flotation, followed by separation of the individual minerals.
— With respect to the flotation of copper–lead–zinc sulfide ores, copper–lead mixed flotation is the most common method used to obtain a copper–lead concentrate [5]. Therefore, the separation of chalcopyrite and galena from a mixed concentrate is necessary. Depressants are a good choice to prevent galena from floating [6].
