However, they are dispersed and their concentration on the earths crust is very low and therefore they cannot be easily exploited. In addition, each rare earth deposit is unique and contains unalike ore bodies which contains several rare earth elements in varying proportions. Rare earth elements do not occur naturally in elemental state as most metallic elements but are found in a large number of minerals types including halides, oxides, carbonate, phosphate and silicate (Eriksson and Olsson 5). In this project we want to address ore dressing as one of the aspects of chemical substance bidding of obtaining rare earths form the naturally occurring ores.Beneficiation is the second step of mining after the ore is removed from the ground. Beneficiation process is divided into two steps i.e. physical be neficiation and chemical beneficiation. Chemical beneficiation is applied after the physical beneficiation. Depending on the composition of the ore, different chemical techniques can be applied to separate the rare earth elements from other minerals contained in the ore. There are various types of ore bodies which include monazite, euxenite, gadolinite, xenotime, bastnasite, and Elliot lake uranium (Gupta and Krishnamurthy149). Different ore bodies take for different compositions and hence different chemical beneficiation processes.There are two different chemical beneficiation ways of obtaining rare earth elements from monazite ore. This conflict comes from the fact that either sulphuric acid or hydroxide can be used to first attack the ore (Gupta and Krishnamurthy 149).Acid treatment. In this treatment (see fig.1), punishing sulphuric acid is used to heat the monazite sand up to a temperature of between 120 and 150C ( Bongaerts 67). Both thorium and
