FROTH FLOTATION AND APPARATUS FOR SAME - Patent application. Other resource industries also use froth flotation to separate such things as oil from sand or waste, ink from a pulp and waste from pulp in the pulp and paper industry.The most common next unit of operation used to achieve such separation is called froth flotation.

Oct 01, 2010 The aqueous medium contains dispersing/wetting agents and collectors. The slurry was then subjected to froth flotation to separate coarse sand from bitumen and sand bearing bitumen. It was determined that milling of the tar sand slurry to break down the aggregates of mineral grains aids in the separation of the bitumenRead More
Froth flotation is a separation process used in a number of applications worldwide. Recycled paper deinking, water purification, bitumen recovery from oil sands and, in particular, mineral separation, benefit from this industrial operationRead More
Satisfactory froth flotation separation may be obtained when water is mixed with the tar sand in the range of about 275 parts to about 325 parts water based on 100 parts of raw tar sand by weight, and preferably the slurry is a 1:3 ratio of raw tar sand to water by weight. In the later flotation zones, higher percentages of water may be utilizedRead More
A method of separating heavy mineral particles, such as zircon, monazites, xenotime etc., from a sample of quartz crystal powder, comprises the steps of: a. conditioning the quartz powder suspected of containing heavy mineral particles as an aqueous pulp using a froth-flotation agent; b. subjecting the conditioned pulp to froth flotation to obtain a tailing; c. combining the tailing with anRead More
Jun 01, 2020 Differently, froth flotation, based on selective attachment of bubbles on plastic surface, is a highly efficient process for plastic separation, where hydrophilic plastics become sunken components, and hydrophobic plastics float with foams (Liu et al., 2019b, Liu et al., 2019a). Considering the inherent hydrophobicity of plastic, a hydrophilicRead More
An improved process for the separation of feldspar from an ore containing feldspar and siliceous sand by means of froth flotation wherein a mixture of a petroleum sulfonate and an N-higher alkyl-alkylenediamine salt which may contain a higher alkylamine is used as a flotation reagent in the presence of hydrochloric acidRead More
Mar 08, 2016 Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product streamRead More
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This method of froth floatation is a method of mineral processing in which different minerals are separated selectively. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted byRead More
Froth flotation is one of these techniques, which is based on hydrophobicity differences between particles. Unlike minerals, most of the plastics are naturally hydrophobic, thus requiring the addition of chemicals that promote the selective wettability of one of its components, for a flotation separationRead More
Dec 22, 2020 Dec 22, 2020 Froth flotation machine is generally used for the concentration of sulphide ores. The principle behind froth flotation process is that sulphide ores are preferentially wetted by pine oil whereas gangue articles are wetted by water. In this process, the suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids andRead More
Nov 23, 2020 Flotation is one of the commonly used methods for silica sand beneficiation. It is mainly used to remove mica and feldspar minerals that are symbiotic with silica sand. However, in the actual production process, the flotation process will be affected by many factors, including: feed size, slurry temperature, slurry liquid chemical composition, flotation reagents and other flotation conditionsRead More
Feb 26, 2017 Feb 26, 2017 The Froth Flotation Machine and its operating principles are universally used for all types of flotation problems.This machine finds a wide acceptance due to its flexibility in construction, which allows the machine to be adjusted to handle pulps with divergent physical characteristics, as well as the common and intricate metallurgical problems which confront the presentRead More
This separation and concentration of copper and moly is called the coppermoly flotation circuit, and is made up of a number of steps. Various equipment is used throughout this process, depending on project needs and circuit design, but can include sludge pump skid, underflow pump skid, sand pump, diaphragm pump, rotary vacuum filter, flotationRead More
