theoretical grade recovery curve cupper flotation

Aug 01, 2013 The results of flotation of different copper ores plotted as the grade-recovery curves with indicated characteristic points such as theoretical (β t) and practical (β p) maximum contents of Cu in the concentrate (grades), maximum curvature (break point, ε b), liberation degree (L p), and maximum Cu recovery to concentrate (ε α) are presented in Fig. 4a–f and Table 1. Since six products of flotation were produced during each experiment, the results are plotted as cumulative grades

    Flotation Circuit: Concentrate Grade and Recovery

    Jun 19, 2013 The texture of particles within a flotation cell play a pivotal role in both mineral recovery, and the grade, in the flotation concentrate. Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade-recovery possible for a given feed ore. Comparing this ‘theoretical’ curve to actual grade recovery will provide insight in to the efficiency of the flotation circuit

    Feb 07, 2014 THEORETICAL Limiting Grade Recovery Curve. To generate a limiting grade-recovery curve, three points are shown for each mineral. The left most end point of the curve represents the feed grade of the composite. The middle point of each curve represents the concentrate grade produced when all of the particles bearing target mineral are recovered

    An Overview of Optimizing Strategies for Flotation Banks

    A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited. Mathematical analysis has shown that a

    For copper, the maximum final grade was observed for sample S5 with 34.8% Cu and a recovery of 71.2%. The maximum copper recovery was observed for sample S8, with 89.8% copper recovery and a grade of 12.6% Cu. For both copper and cobalt, it can be expected that mineralogical properties have influenced the differences in grade recovery curves

    The influence of textural variation and gangue mineralogy

    Mineralogy and critically the texture of both the ore and gangue phases are of paramount importance in the flotation recovery of copper from porphyry ores. Mineralogy and texture will define the theoretical grade recovery curve for a feed ore. Actual grade-recovery falling below this may be due to texture and gangue influences, whilst desired grade-recovery above this line will not be possible
