It is also flexible and thick because of the vegetable tanning. This type of leather feels good and molds well. People with chemical sensitivities may have fewer problems with leather produced in this manner because the vegetable tanning process may help remove some of the chemicals used in the chrome tanning process. Conclusion
NPTEL Chemical Engineering Interfacial Engineering Module 6: Lecture 6 Joint Initiative of IITs and IISc Funded by MHRD 3/20 6.6.1 Introduction Flotation is a process of separation and concentration based on differences in the physicochemical properties of interfaces.
In this study, a combined process of gravity separation and flotation was proposed for the reutilization of spent magnesia-chrome refractories. This process can effectively recycle the metals contained in spent refractories, whereas refractories with minor or trace metal impurities can be used as raw materials for renewable refractories.
Dissolved air flotation (DAF) is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water – then releases it at atmospheric pressure.
A new depressant for use in enhanced separation of polymetallic sulphides is described. The depressant agent is used in conjunction with conventional collector agents and frothing agents in the flotation separation of copper, nickel, lead, zinc sulphides by depressing iron sulphides such as pyrrhotite, pyrite and marcasite in the tailing.
The use of chemical flocculants with DAF is based on system efficiency, application (use of DAF) and cost. Commonly used chemicals include trivalent metallic salts of iron, such as FeCI2 or FeSO4 or aluminum, such as AISO4. Organic and inorganic polymers (cationic or anionic) are often used to enhance the DAF process.

Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes.
