Table of ContentsChemistry of Sodium SulfideSulfidization Sodium Sulfide in Sulfide Minerals Flotation Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. The sulfidization process, developed in the in 191520 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in ...
Inhibiting the flotation of iron sulfide minerals. When flotation of various nonferrous metal sulfide minerals (such as copper, lead, zinc, etc.) with xanthate collectors, the ore usually contains a certain amount of iron sulfide minerals, such as pyrite, marcasite, pyrrhotite, arsenopyrite, etc., inhibiting iron sulfide minerals with lime ...
Jul 27, 2020· Leadzinc ores are usually upgraded by the froth flotation method and sometimes by a gravity concentration prior to flotation. When Pb/Znbearing minerals are well released from each other, the concentrates contain up to 74% Pb and 65% Zn for sulphide ores, 55% Pb, and 40% Zn for oxides.

As an example, sodium ethyl xanthate may be added as a collector in the selective flotation of galena (lead sulfide) to separate it from sphalerite (zinc sulfide). This slurry (more properly called the pulp) of hydrophobic particles and hydrophilic particles is then introduced to tanks known as flotation cells that are aerated to produce bubbles.
A new flowsheet was developed to recover the valuable minerals from oxide or oxidesulfide ores of lead and zinc. The flowsheet consisted of flotation of sulfide minerals, desliming and ...

For example, in the flotation of leadzinc sulfide ore, it is necessary to separate lead, zinc and sulfur. At this time, flotation reagents are used to change the nature of one of the minerals and separate them one by one. In the case of leadzinc separation, the "zincinhibited and leadcollected" program is .
Feb 15, 2019· 1. Introduction. Lead is an important base metal which is commonly used in batteries, alloys, as well as other industries [].Lead is conventionally produced from lead sulphide minerals (galena) [2,3].However, lead oxide minerals are selected as potential resources for the lead extraction due to the depletion of lead sulfide ores [4,5].Cerussite, is a typical lead oxide mineral and flotation is ...
Oct 01, 2012· The flotation of smithsonite from tailing which comes from the cerussite flotation circuit was investigated using Armac C and Armac T as amine collectors. The results indicated that the dosage of sodium sulfide, collector type, and desliming are the main affecting factors on the Zn grade and recovery of smithsonite flotation concentrate.
The main usful elements in a flotation tailings in Inner Mongolia were lead, zinc and silver, and the main lead and zinc minerals were oxide minerals. The content of sulfide minerals of lead and zinc especially sulfide mineral of lead were small,so It was difficult to get concentrate of sulfide mineral of flotation tailings was used as the
