ABSTRACT
The present Atlas (Part III) is the last from a series of articles on upgrading curves relating quality and quantity of products of separation. In this Atlas 12 additional upgrading curves were presented while 30 curves were presented in Parts I and II. In the previous papers the curves were grouped into categories: A/ (α-insensitive curves with triangle or near triangle area accessible for plotting) Ao (α- insensitive curves with square area available for plotting) B/ (α-sensitive curves with triangle plotting area, Bo (α-sensitive curves having square plotting area), C/ (α-insensitive curves for β >α and trian- gle area for plotting), and Co (α-insensitive curves for β >α or β <α and square area) where β stands for the content of a component in concentrate while α is the content of a component in the feed. In this Part III more complex upgrading curves were presented and an additional class of upgrading curves was introduced with irregular area for plotting. It was again stressed that all the upgrading curves contain the same information but in a different, specific for a given curve form. The use of upgrading curves depends on the needs and preferences of users. An appropriate matching of an upgrading plot with a set of separation results allows to approximate the curve with a suitable mathematical formula which can be used for characterizing separation. As previously, the readers are kindly asked to report unmentioned hitherto upgrading curves to jan.drzymala @pwr.wroc.pl for their future publication in the Internet http://www.ig.pwr.wroc.pl/minproc/krzywe%20wzbogacania.html
