Abstract: Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step. The first step comprises conditioning a pulp of the ore in the presence of at least one alkaline agent selected from a group of agents which is defined in the specification which follows. The pulp is then further conditioned in the presence of a member of the xanthate family of flotation reagents and sufficient dispersing agent to effectively disperse the host rock minerals. The resulting pulp is then subjected to froth flotation. Preferably there are three separate conditioning steps, namely conditioning carried out in the presence of (1) one of the hereinafter defined alkaline agents, (2) a member of the xanthate family of flotation reagents, and (3) sodium silicate. The invention is particularly valuable for the recovery of metallic sulphides from ores containing talcy minerals or natural slimes and the invention has been applied with signal success to the flotation of copper-nickel sulphide ores containing over 40 percent weight of talcose host rock minerals.
Abstract translation: 通过其中在泡沫浮选步骤之前进行两个或更多个调节步骤的方法,从其矿石中浮选硫化物矿物。 第一步包括在至少一种选自以下说明书中定义的一组试剂的碱性试剂的存在下调节矿石的纸浆。 然后在浮选试剂的黄原酸盐族成分和足够的分散剂的存在下进一步调节纸浆以有效地分散主体岩石矿物。 然后将所得纸浆进行泡沫浮选。 优选地,存在三个单独的调节步骤,即在(1)下列定义的碱性试剂之一中进行调理,(2)浮选试剂的黄原酸盐族的成员和(3)硅酸钠。 本发明对于从含有矿物矿物或天然矿石的矿石中回收金属硫化物是特别有价值的,并且本发明已被应用于含有超过40重量%的滑石糖主体岩石矿物的铜 - 镍硫化物矿石的浮选。

Abstract: The invention is primarily directed to the production of a substantially iron free alumina-silica product and substantially iron free aluminum chloride from bauxites, bauxitic clays and kaolinitic clays wherein the feed material to an agglomeration stage is selected to contain a minimum of about 20% kaolinite mineral. The agglomerates are so formed to produce a product that is preferably at least minus 6 mesh plus 200 mesh and in a subsequent calcination stage the calcined agglomerates have a bulk density of preferably 0.8 to 1.3. In a subsequent differential iron chlorination stage a substantially iron free alumina-silica product is produced and in a subsequent mass chlorination stage substantially iron free aluminum chloride is produced.
