Overview of Ore Deposit Models. An ore deposit is a geological anomaly in which metals have been concentrated in a higher abundance than that of the neighboring parent rock. Ore is a classification of rock that describes an economically viable block, from which metal or minerals can be extracted profitably. An ore deposit model is an extensive ...

concentration in placer deposits. In sand deposits ilmenite exhibits various degrees of alteration as a result of oxidation and preferential leaching of iron. Sand ilmenite concentrates may therefore vary widely in grade, ranging from about 48 percent Ti0 2 for essentially unaltered South Afri-can ilmenites to 61 to 64 percent Ti0 2

Table 1 shows the semi-quantitative results of the P 2 O 5, Fe 2 O 3, and TiO 2 contents obtained via XRF for samples AM1, AM2, and AM3, respectively. These three samples had a high Fe 2 O 3 content, in which sample AM2 was the highest. P 2 O 5 content was low in all three samples, which reveal the useful element losses in the magnetic separation step of the phosphatic ore.

Abstract: Since the physical and chemical properties of apatite and dolomite can be similar, the separation of these two minerals is difficult. Therefore, when performing this separation using the flotation method, it is necessary to search for selective depressants. An experimental research was performed on the separation behavior of apatite and dolomite using calcium lignosulfonate as a ...
