(PDF) Celestite-Gypsum separation by flotation

Flotation behaviour of pure minerals, celestite and gypsum was investigated using oleate and sulphonate as collectors in a Hallimond tube. The zeta potential values of both minerals were measured...

Bioleaching of copper ore flotation concentrates

Jan 01, 2003 Compared with other copper sulfide concentrates the Polish copper flotation concentrate contains carbonate minerals, such as dolomite and calcite. The microscopic observation revealed that the gypsum precipitation occurred during a bioleaching process. However, this precipitation may not be valid because the gypsum aggregates were porous.

Acid treatment of copper sulfide middlings and rougher

Aug 01, 2008 Separation of metal-bearing sulfides from gypsum by means of xanthate flotation of chemically modified final concentrate from Polkowice plant leached with Rw = 70% (called “gypsum flotation”), fully confirmed the capability of the acid leaching as a concentrate upgrading method.

Froth Flotation Principles

Flotation has been successfully used in Canada for removal of impurities from sodium chloride. In this particular case anhydrite and gypsum are recovered in a flotation concentrate which is dis-carded to waste, while the tailing is a high-grade salt product free from impurities.

Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product.

US6098810A Flotation process for separating silica from

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

Copper Flotation Mineral Processing & Metallurgy

Mar 19, 2017 The concentrates from rougher flotation cells are sent directly to regrind. Often the grind is 200-mesh. After regrind is flotation cleaning. In some cases the concentrate from the first three or four rougher flotation cells can be sent directly to cleaning without regrinding.

The interaction of clay minerals with gypsum and its

Jun 01, 2015 The true flotation recoveries for the mixtures with clay minerals and gypsum were close to the baseline (about 91%) except for the flotation of ore–bentonite mixture that produced much lower copper recovery by true flotation (82%).

Extraction of lithium from micaceous waste from china clay

Nov 01, 2011 A further experiment was carried out using the mica flotation concentrate (i.e. prior to magnetic separation. Using a mica:gypsum weight ratio of 2:1 and a roasting temperature of 1050 °C the average lithium and rubidium extractions from replicate tests were 63% and 18% respectively. This suggested a lower lithium extraction results from the

Gypsum is fine grained in nature and is beneficiated by flotation only. Both the minerals find extensive use in the fertilizer industry and a minor quantity in the manufacture of plaster of paris and cement industry. Similar tests conducted at 10 mm size yielded a product analysing 45.65% SO3 and 0.31% insolubles with 97.7% SO3 distribution in it.
