Researches On Copper. History & Metallurgy, Fathi Habashi Feb 2009

Researches On Copper. History & Metallurgy, Fathi Habashi

Fathi Habashi

The present volume is a collection of selected papers dealing with the extractive metallurgy of copper published by the author and his coworkers. They are reproduced here in a facsimile edition in 240 pages. In addition ten new chapters were specially written in 150 pages. The book is fully illustrated by many colored pictures, flowsheets, and diagrams. It is hoped that it will be useful for students, engineers, chemists, geologists, and for research workers.

Leaching Of Copper(I) Sulphide By Sulphuric Acid Solution With Addition Of Sodium Nitrate, Zeljko J. Kamberovic Jan 2003

Leaching Of Copper(I) Sulphide By Sulphuric Acid Solution With Addition Of Sodium Nitrate, Zeljko J. Kamberovic

Zeljko J Kamberovic

Finely grained samples of copper(I) sulphide were leached by H2SO4 solution with added NaNO3. The occurrence probability of chemical reactions was analysed based on literature data and products which were formed during the process and the overall leaching reaction was defined. The effect of temperature, concentration of NaNO3 and H2SO4, stirring speed, phase ratio and time, on the leaching degree of copper was studied. The quantity of copper dissolved increases with growth of the values of all the parameters. Kinetic analysis shows that the leaching mechanism is very complex. By using appropriate mathematical kinetic models, it is found that the …
