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 acid According to this improved process feldspar with good quality
·Quartz and feldspar are usually exist in symbiosis in nature and they are difficult to be separated effectively by conventional physical methods owing to their similarities in crystal structures and surface characteristics Flotation is the most resultful method and especially flotation with hydrofluoric acid HF is the most efficient way Because HF may cause serious
·Feldspar is a common occurrence in spodumene ores and has applications in glass making K feldspar is a key component in the manufacturing of ceramic materials Froth flotation is the main method used for the recovery of feldspar from lithium ores because its flotation properties are well understood Fuerstenau and Pradip 2005 Beryl which
·The flotation process to separate feldspar from quartz was developed in the 1930s [1] Since then many papers have been published on the application of different collectors
·Two representative feldspar ore samples taken from the Milas Mugla region in Turkey were separately tested for desliming and flotation by conventional and ultrasonic methods under similar
A froth flotation process is used for most feldspar ore beneficiation Figure 1 shows a process flow diagram of the flotation process The ore is crushed by primary and secondary crushers and ground by jaw crushers cone crushers and rod mills until it is reduced to less than 841 µm 20 mesh
A separation process is provided for treating a feed material comprising silica feldspar and metal impurities including at least one of mica iron impurities or refractory heavy minerals to form one or more products for use in making glass In the process the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate
·This study shows very slow dissolution reaction kinetics for spodumene and feldspar This observation is in contradiction with other kind of minerals such as salt type minerals where there is an impact of this dissolution reaction on the flotation process Moreover Brantley 2008 has resumed studies on mineral dissolution kinetics in water
·A major proportion of feldspar ores contain both Na feldspar Albite and K feldspar microcline or orthoclase in the same matrix usually in quantities of about 3 5% Na2O and K2O
·The most common beneficiation method for feldspar is flotation with a cationic amine collector under acidic conditions However there are several disadvantages to this such as environmental pollution and equipment corrosion In order to resolve such problems it is important to study the flotation of feldspar using anionic collectors under natural pH conditions
·In recently years scholars have carried out numerous researches in order to enhance the flotation separation of spodumene and feldspar To date the researches in academic circles prevailingly are absorbed in two aspects pre desliming flotation and direct flotation [14] [15] With the development of flotation reagents more and more attentions are focused on the
·Froth Flotation is a very important process in the field of mineral processing which is utilized for the purpose of extraction of minerals from Ore It is a part of surface chemistry in which we selectively separate the minerals from the unwanted material This process is used in a variety of industries and is very crucial in each one of them
·Flotation experiments performed on a quartz feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid HF simply by the aid of a
·Gold flotation process is a kind of beneficiation method that makes the useful gold mineral adhere to the bubble to achieve gold enrichment by means of the different physical and chemical properties of the ore surface gold ore blende galena and hematite and gangue minerals quartz sericite feldspar calcite chlorite zircon and apatite
·The principal impurities in some feldspar ores are titanium and iron which impart color and degrade the quality of the ore Mineralogical investigations indicate that while titanium originates mainly from rutile with small amounts of sphene iron originates mainly from mica minerals Fatty acids particularly oleic acid are extensively used with reasonable success in
