2019-1-21 · lead in the leach liquor was separated out as PbCl 2 by natural cooling. Ninety-five percent of silver in mother liquor was recovered by cementation with a lead sheet. The depleted CaCl 2 solution can be sent to the leaching step again to close the loop. Keywords: bismuth, zinc, lead, silver, extraction and separation. 1. Introduction

Hydrometallurgy - an overview | ScienceDirect Topics

The commonly used raw materials for the extraction of niobium are ores and slags from tin production. In case of the mineral pyrochlore, Ca 2 Nb 2 O 7, pyrometallurgical treatment by sintering and melting removes detrimental impurities such as sulfur, phosphorus, and lead from the physically enriched ore. The obtained synthetic niobium ...
