Application of Cellulose Derivatives in Mineral

2021-6-1 Therefore, Cellulose derivatives (CDs), high-molecular-weight condensation polymers made up of basic monosaccharide sugar units, has been applied in mineral processing. Although there were many different types of polysaccharides including their derivatives in nature, wildly have been used in the mineral industry, especially in flotation.

Flotation Optimisers to Increase Recovery and Grade

Our flotation depressants are proven to be effective on a variety of gangue minerals: Sulfide minerals, like pyrite, pyrrhotite, arsenic and bismuth sulfides. Oxide minerals, like silicates, talc and calcite. Clays and graphite. Sulfate minerals, like baryte and gypsum. Check availability and packaging.

Carboxymethyl Cellulose (CMC) Mixing Systems

2021-7-1 I have developed a flowsheet to treat a copper sulphide ore that contains a significant level of talc. The flowsheet calls for doses of carboxymethyl cellulose (CMC) in excess of 300g/t to produce a saleable concentrate. The CMC will be purchased as a powder and will need to be mixed on site prior to being dosed to the process.

2021-6-3 The froth flotation process uses chemicals manufactured from fossil materials. In most cases, the frothing agents consist of sidestreams of crude oil processing, including various polyglycols and alcohols. Researchers at Aalto University have developed a cellulose-based compound which may be used to replace traditional frothing agents.

WO2013120689A1 Mineral ore flotation using

A flotation method for mineral processing is disclosed. The method for floating comprises a first step comprises using a first carboxymethyl cellulose (CMC) in a first flotation cell, and a subsequent step comprises using a second CMC in a subsequent flotation cell, the first and second CMCs having different characteristics. The first CMC has a degree of substitution (DS) that is different
