`J <br />NALCO 88Td is a high molecular weight liquid flocculent designed /or <br />mineral processing selling and filtration operations. <br />/ts sing/e-component, liquid form provides the following advantages over <br />dry polymers. <br />• Dissolves immediately <br />• Eliminates "fish-eyes" that occur with undissolved dry product <br />• Arrmits safe end easy dust-fiee handling <br />• Allows automation of make-up systems <br />NALCO 8873 provides maximum performance in systems having a pH <br />greater than 6. <br />PRINCIPAL U8E8 <br />NALCO 8873 was developed to enable rapid solution <br />preparation and to provide maximum activity in mineral <br />processing operations where the pH of the water is <br />greater than 6.0. Typical processes are: <br />• Coal <br />• Sand and gravel <br />• Miscellaneous mineral processing operations <br />NALCO 8673 offers the following benefits in these <br />mining processes: <br />• Clarification of recycle water <br />• Thickening and settling of refuse slimes <br />• Refuse slimes filtration <br />• Mineral concentrate thickening and fihretion <br />GENERAL DE8CRIPTION <br />Odor .............. ............Slight organic <br />Color .............. ..................Cream <br />Form .............. ...Single component liquid <br />Charge in Solution .. ........Moderately anionic <br />Specific Gravity ..... ...............1.02-1.04 <br />Density ............ ...........8.5-8.71b/gal <br />pH (1 °/a Solution) ... .................7.4-7.6 <br />DOSAGE <br />Dosage requirements vary depending upon overall <br />effects desired and total percent solids in the slurry. <br />Typical ranges for mineral applications are: <br />Thin slurry thickening and clarification ....0.5-10 ppm <br />Heavy slurry filtration .....0.005-5 lb/ton of dry solids <br />NALCO CHEMICAL COMPANY <br />MINING 4N0 MINlR4l Pq OCHBBINL) CMlMICPI• <br />2901 BU TT ERFIEL^ ROgO "I OLK 9ROO K.

A <br />centrrfugal pump may be used to transfer solutions of <br />8873 from one tnnk to another. A positive displacement <br />pump is strongly recommended for metering and <br />feeding solutions of 8673. Recirculation should be <br />avoided. <br />The stock solution should be metered into a mixing tee <br />and water tine for continuous dilution to 0.1 % or less <br />upstream from the point of addition. Individual process <br />applications may, require greater dilution to optimize <br />product performance. Feed the diluted 8873 in a manner <br />that provides maximum distribution to the slurry solids <br />and minimizes shear. This is best accomplished with a <br />distribution header. In addition multiple feed points can <br />increase the polymer's effectiveness. <br />Carbon steel tanks and pumps may be used for <br />solutions of 8873. Galvanized metals and natural or <br />synthetic rubbers should be avoided. Teflon or other <br />inert materials should be used for gaskets and pump <br />seals. <br />SNIPPING <br />NALCO 8873 is shipped in 55-gallon, non-returnable, <br />lined steel drums containing approximately 470 pounds <br />net and 5-gallon pails of 43 pounds net. It is also <br />available in bulk quantities. <br />(Continued on Reverse Side) <br />8873 <br />
