Abstract:
There is described herein a method and system for determining a dosing of a binding agent for combining with a particulate material to produce an electrode. Two indices, namely a simulated baked density and an image characteristic, are obtained from an unbaked electrode of a batch N. The indices and data from batches N and N-1 are used in order to determine a dosing of the binding agent for batch N+1.
Abstract:
The present invention describes a process for producing a bauxite agglomerate comprising: providing a crude bauxite having a fine particle size and an initial weight % of water as a feed bauxite, optionally screening said feed bauxite or pre-screening at least part of said crude bauxite, optionally adjusting the weight % of water of the feed bauxite; providing a cement binder; mixing a feedstock bauxite based on said feed bauxite with the cement binder in at least one mixer under intensive mixing conditions producing a bauxite binder mixture; and curing the bauxite binder mixture for a cure time thereby allowing the cement binder through a reaction with the water in the bauxite binder mixture to cure and form the bauxite agglomerate. The process enhancing the value of crude bauxite, by producing a transportable agglomerated crude bauxite from a fine non-calcined bauxite. The bauxite agglomerate serving as an intermediate product for producing a smelter grade alumina.
