Assessment of water quality effects on flotation of

15/10/2014 The variation in flotation process water quality reflects on metallurgical results. Thiosulphate presence depending on concentration promotes or hinders cobalt and copper flotation. Abstract. Results from lab scale flotation show that when process water was re-used copper and cobalt recovery from an oxidized ore decreased respectively with 25% and 30% at the rougher stage

Water quality effects on flotation: Impacts and control

15/08/2018 The quality of the water plays an important role in determining the performance of the flotation process. This has led to significant amount of research initiatives dealing with the impact of water re-use and water quality on flotation. Summaries of the findings have been published by Rao and Finch, 1989, Johnson, 2003, Liu et al., 2013. There

THE INFLUENCE OF WATER QUALITY ON THE

The effect of recycling the water used for flotation on the water quality is summarised in figure 6. The results are rather disappointing in the sense that the hydrolysis of most of the metal cations at pH 9.18 caused their concentrations to be generally below the detection limit of typically 0.02 mg/L. This is unfortunate as a cation like the cuprous ion will certainly be capable of

Froth Flotation an overview ScienceDirect Topics

Copper (or metal) recovery percentages of the flotation circuits of a copper mine/mill are extremely important. For example, it is estimated that for a plant processing 50,000 tonnes of ore containing 1% copper per day, increasing the copper recovery from 86 to 87% of that contained in the ore could increase revenues by approximately $4 million annually.

Estimated Water Requirements for the Conventional

This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to compensate for water losses. Much of the global supply of copper originates from mines that also produce byproduct molybdenum, but for simplicity, a single copper concentrate has been modeled for this

Froth Flotation Process Mineral Processing & Metallurgy

20/01/2021 Froth Flotation Handbook The copper concentrate from a copper lead zinc flotation circuit. Froth flotation, as pointed out previously, was a part of the evolution of milling during the first quarter of the 20th century—a period during which the progress of milling was greater than in all of its previous history. It marks the passing of the stamp battery, after 400 years service to the mining

COPPER MINERALS FLOTATION IN FLOTATION PLANT OF THE

copper concentrate quality due to extended cleaning time was the goal of the research. Flotation experiments of cleaning copper concentrate were carried out by the following conditions: in function of cleaning time (1,2 and 3 min) with solid-in-pulp concentration

The impact of water quality on flotation performance

The impact of water quality on flotation performance by G. Levay*, R.St.C. Smart † and W.M. Skinner† Synopsis Water represents 80–85% of the volume of mineral pulp processed in flotation circuits. Imperatives for a more detailed focus on circuit water quality and its control have come from increasing requirements to use relatively impure primary water supplies (e.g. high salinity

A review of the effect of water quality on flotation

Again, research results indicate that fluctuations in water quality do influence flotation performance, but to a different degree depending on the type of ore treated and the set of reagents used

The Bulgarian site is the first Aurubis primary smelter to successfully complete the Copper Mark certification process and now bears the quality seal. The certification verifies that Aurubis Bulgaria produces copper sustainably.

Dissolved Air Flotation Systems (DAF) Remove TSS, BOD

Dissolved Air Flotation is based on a physical / chemical process, where the injection of air into the water stream with chemical assistance causes the particles/flocks to float to the surface. This floating sludge layer is then automatically and continuously removed by a scraper mechanism. The DAF system will produce a treated effluent virtually free of TSS, FOG and remove a large portion of

copper oxide flotation|miningpedia

27/07/2021 just as its name implies, direct flotation is a method of flotation using collectors directly to flotate copper oxide，which is mainly for copper oxide with relatively simple mineral properties and simple structure, where the performance of the collectors is a direct factor affecting its flotation efficiency and quality.

A study of the flotation characteristics of a complex

copper ore comprising sulphide and oxide minerals with a view to achieving an optimal flotation performance in the treatment of the Kansanshi ore body. This required an in-depth analysis of the mineralogy of the feed as well as tailings samples after different flotation processes involving a range of reagent types and dosage procedures. The ore samples studied represented a high

A study of the flotation characteristics of a complex

The quality of an ore at Kansanshi is defined by the acid soluble copper (ASCu) content of the ore, which is used as a proxy for oxide mineral content. An important finding in this study was that sulphide minerals are also prone to digestion during this analysis. Chalcopyrite was the major copper mineral in the HQ ore, constituting 3.9 %, but only 1.0 % of the LQ ore. LQ ore was

(DOC) Employment of the Flotation Method in Copper Country

The advent of the flotation process in Copper Country occurred due to a change in the composition and quality of the copper ore encountered within the mines. All of the copper deposits found in the Keweenaw Peninsula are native copper deposits, or copper that is unalloyed to any other elements1. Native copper is found in three types of deposits, mass,
