      Absorbance (A, y-axis) vs. concentration (x-axis). To do this, absorbance at λ max is measured for each of the diluted standards as well as the undiluted second standard and the two undiluted unknown solutions. It is convenient to express the concentration in terms of % Mn instead of using molar.

The recovery of elemental sulphur and silver as by-products makes the process more economically attractive.

There some important stuff in there. The recovery, in the case of the concentration of a metallic ore, is the percentage of the total metal contained in the ore that is recovered from the concentrate; a recovery of 90% means that 90%.

We represented it as FC -f- AT FT -f By increasing the concentration of ferric chloride (FC) we stimulated the left-to-right reaction, and as we saw, a new state of equilibrium was established.

In the process some FC and AT molecules were used up. Beryllium Bertrandite and beryl ores are treated using two separate processes to produce beryllium sulfate, BeSO4: a counter-current extraction process and the Kjeligren-Sawyer process.

The intermediates from the two ore extraction processes are combined and fed to another extraction process. The book presents a comprehensive, rigorous, but understandable explanation of X-ray physics and the many contexts in which this physics is useful in modern technologies.

Hummer highly recommends this book to any student or researcher with an adequate background in physics who is seeking advanced knowledge of any system that utilizes X-rays.
