2015-11-27 · ： Ore Geology Reviews, 2 (1987) 359-404 Elsevier Science Publishers B.V., Amsterdam- Printed in The Netherlands 359 GENESIS OF NICKEL LATERITES
2017-11-11 · size exerts on the abundance and redistribution of REE in lateritic regolith is not well known. Most of the studies on the geochemical behavior of REE during supergene weathering concentrate on bulk regolith. Therefore, a systematic understanding of the occurrence of REE in different grain size fractions of lateritic regolith is needed.
2007-10-14 · There is an increase in mineral grain size toward the Duluth Complex (Figure 2). The increase in magnetite grain size results in better liberating iron ore. Unfortunately, in this instance, better liberation results in decreased concentrate production. This is counter intuitive. The classifiion circuit is designed to process
2009-1-14 · on facies, grain-size variation, abundance of volcanic quartz grains mapped several gossan and ironstone types at Gossan Hill, based on their mesoscopic fabrics, partly inherited from the parent mineralogy, Lateritic nodules and duricrust Gossan Hill was the test area for initial CSIRO research on geochemical
2018-12-11 · Laterite is a soil and rock type rich in iron and aluminium, and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content.
