Some porphyry copper ores contain naturally floatable gangue minerals, such as chlorites and aluminosilicates, as well as preactivated quartz. Sodium silicate, carboxy methyl-cellulose and dextrins are common depressants used to control gangue flotation. 

The head of a safety match consists of K chlorate 45-55, animal (hide) glue (as a binder) 9-11, sulfur or rosin 3-5, extender (starch, dextrin) 2-3, neutralizer (ZnO.or Ca carbonate) 45-55, infusorial earth 5-6 other siliceous filler 15-32%. Fractional percentages of a soluble burning rate catalyst, such as K di-chromate, also soluble dye stuffs, etc... 

Depressants The purpose of depressants is to inhibit or retard the floatation of a desired type of particle. Its mode of action is to either inhibit the collector molecule from adsorbing onto the particle surface or to mask the adsorbed collector species from the bulk solution so that the particle does not display a hydrophobic exterior surface in contact with bulk solution. Examples of depressants include starch, tannin, silicates, aluminum salts, and dextrin.

This is an example of the use of dextrin with high ratio sodium silicate binder to produce cores which retain excellent strength and hardness when stored for several weeks. 

A sand mix is prepared as described in Example 14 by mixing 14.7 g Ludox HS-40, 16 grams of 50% aqueous solution of dextrin (sold by Industrial Products Chemicals, Pikesville, MD) previously mixed with 40 g of sodium silicate ratio 3.25 (Du Pont No. 9), 760g of Portage 515 sand. Standard cores are prepared and set...

Binder. A substance added to a ceramic raw material of low plasticity to facilitate its shaping and to give the shaped ware sufficient strength to be handled materials commonly used for this purpose include sulphite lye, sodium silicate, molasses, dextrin, starch, gelatine, etc. The term bond (q.v.) is also sometimes used in this sense but is better reserved to denote the intergranular material that gives strength to the fired ware. 

Lamination of Paper and Board. Adhesives based on starch, dextrin, glutin and poly(vinyl alcohol), and also emulsion adhesives, mainly polyfvinyl acetate), are used for the lamination of paper and board. Only when high initial tack and a lay-flat effect are required are hot glues based on glutin still in use. Starch-based adhesives modified with silicate, casein-stabilized copolymer dispersions, and rubber latices are used in the lamination of paper to aluminum foils. Modified polyacrylate solutions and reactive polyurethane adhesives are used mainly for paper-to-plastic lamination. 

Water is not only the carrier for latexes but is also the most important of the solvents. Starches and dextrins, protein glues, and polyvinyl alcohol are the more significant water-soluble organic adhesives. Sodium silicates, comprising the most important family of inorganic adhesives, are water soluble. 

The tackified polyvinyl alcohols, introduced in the early 1960s, rapidly replaced starch/urea formaldehyde adhesives in solid fiber laminating and dextrine, compounded polyvinyl acetate and sodium silicate adhesives in spiral tube winding. The new adhesives demonstrated superior adhesion over silicates and dextrines to a wide variety of paper substrates. These adhesives reduce warp in solid fiber laminating and shrinkage in spiral tubes because of the low adhesive application rate and, thus, low amount of water added to the laminations. The low application rate and low resin level also made these adhesives very economical. 

Rubber and cellulosic-type solvent cements are used for attaching gaskets and blotters. Water based adhesives such as sodium silicate, starch, dextrin, and latex are used for a variety of applications such as labeling.
