| Abstract: | In order to develop and utilize the resources of a beach placer,the experiment and research on the process of pre-concentration were carried out,and the suitable test equipment and process parameters were determined.When the feed concentration of roughing spiral ore is 25% and the processing capacity is about 2 t/h,titanium concentrate products with TiO2 grade of 27.07% and TiO2 recovery rate of 88.92% can be obtained through the spiral chute process of 1 coarse separation and 1 selective reseparation.The research results provide data support and technical support for the subsequent processing of this resource. |
