  • Optimizing The Rougher Flotation Process Of Copper Ore

    Feb 22, 2019 Correlation is used to find the process variables that affect the grade copper and recovery. Some of the factors that are studied as input variables are the copper grade of the ore at the entrance of the flotation process, the amount of reagents and foaming agent used, and the granulometry, among others.

  • Flotation Of Copper Ores 911 Metallurgist

    Feb 11, 2016 The first pneumatic-flotation plant in this country was erected by me in February 1914 for the National Copper Company at Mullan, Idaho, a description of which has already been published. The results were fully up to expectations from the very start. This plant consists of 8 rougher and 2 cleaner cells and treated 500 tons per 24 hours.

  • Flotation Of Copper Ore In A Pneumatic Flotation Cell

  • 60 Centuries Of Copper The Flotation Process

    The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores which would be regarded as relatively rich in copper are scarce the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper.

    Table 5 presents the first order flotation rate constant, the maximum theoretical flotation recovery, and the coefficient of variation of the rate constant, obtained from the data of rougher flotation of a copper sulphide ore with 10 ww biosolids, 1.5 ww salt of humic acids, and a mixture of conventional collectors and frothers used in the

  • The Effect Of Oxidation On The Flotation Behaviour Of

    In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.

  • Pdf Characteristics Of Modern Copper Flotation

    In general, most porphyry copper ore bodies are processed at high tonnage through several parallel banks of cells at each stage of flotation. The floatability parameters of these copper ores are very similar in terms of rate of flotation and proportion of fast, slow and non-floating material.
