[0008] The compositions useful as grinding aids in mining operations comprise hydrolyzed starch. These compositions are typically added to mineral slurry prior to or during a grinding stage in a mineral ore recovery process. Thus, the invention encompasses use of a composition comprising a hydrolyzed starch for reducing the stickiness, energy of
Once an aqueous mixture of the mineral ore particles is prepared, a variety of individual events can occur. Mediumsized particles,, 100 µm in diameter, will settle in a few seconds by gravity (, Stokes Law) unless agitation is present or the slurry is very thick [contains a yield value as described in Klimpel (1982 and 1982/83)].

In an aspect of the invention, the grinding aid composition is added to the mineral slurry, which is the aqueous slurry comprising the mineral ore, in an amount of about % to about % by dry weight of the mineral ore, preferably in an amount of about % to about % by dry weight of the mineral ore.
The general use of chemical grinding aids involving several different mechanisms for increasing throughput in the wet grinding of ores has been discussed in a number of recent publications. It appears from industrial scale testing that the use of selective dispersants with certain prespecified operating conditions is an approach which can produce two important results: first, increased feed ...

Mineral Processing and Ore Dressing. Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs.

Iron ore is a mineral aggregate containing iron elements or iron compounds that can be economically utilized. Any ore containing economically available iron is called iron ore. There are many kinds of iron ores. The main 4 types of iron ores are Magnetite (Fe3O4), Hematite (Fe2O3), Limonite (Fe2O3．nH2O), and Siderite (FeCO3).
Grinding equipment. Grinding equipment is the key equipment for crushing materials after they are crushed. The ball mill can process various grinding minerals, nonferrous metal beneficiation, and new building materials. It is often combined with a spiral classifier to form a closedcircuit ring mill, which has higher fine powder and grinding ...
L'invention concerne des compositions d'adjuvants de broyage comprenant des amidons hydrolysés, tels que des solides à base de dextrine, de maltodextrine ou de sirop de maïs. Ces compositions d'adjuvants de broyage sont typiquement ajoutées à plusieurs boues de minerais avant les opérations de broyage afin de modifier les caractéristiques rhéologiques de ces boues de minerais.
