Froth flotation of ores - PETROVICH; VOJISLAV

Zinc, bismuth, cobalt, and nickel ores were successfully concentrated by froth flotation method when occured in simple sulfidic ores such as lead, copper, pyrite ores. Bismuth in lead concentrate treated metallurgically yield lead-bismuth alloy, which alloy is thereon treated by a metallurgical process to obtain pure bismuth metal.

CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION

2020-5-6  A. Vidyadhar and R. Singh INTRODUCTION Froth flotation is a process used to separate minerals, suspended in liquids, by attaching them to gas bubbles to provide selective levitation of the solid particles. It is most extensively used process for the separation of chemically similar minerals, and to concentrate ores for economical smelting.
