Note that: in Table 1, other rubidium mineral contribution ratio CR n Expressed as the contribution rate of rubidium minerals (albite, etc.) in addition to mica and potassium feldspar.
As can be seen from table 1, the results of the single-mineral rubidium contribution obtained by volume fraction or mass fraction are close in ten phases, with consistency. The proportion of mica rubidium in the granite rubidium mineralization point is 7.15-96.91% (or 7.54-99.16%), and the proportion of mica rubidium is sequentially increased (7.15% -21.02% -51.85% -96.91% or 7.54% -22.51% -49.45% -99.16%) along with the change of ore types from white granite to secondary granite to changed biotite secondary granite to mica. The proportion of potassium feldspar rubidium in the granite rubidium mineralization point is 48.16-0.01 percent (or 51.51-0.01 percent), and the proportion of the potassium feldspar rubidium is sequentially reduced (48.16 percent to 58.56 percent to 29.96 percent to 0.01 percent or 51.51 percent to 65.13 percent to 33.96 percent to 0.01 percent) along with the ore type change from white granite to double-long granite to changed biotite double-long granite to cloud-English rock. According to the characteristics that feldspar and rubidium are difficult to extract relative to mica and rubidium, the mica and rubidium mineralization point has high mica and rubidium ratio (especially, mica rock and changed biotite granite), high extractability and good development and utilization prospects are indicated. Combining with the current rubidium extraction process, the rubidium contribution rate in the white hillock rock is low in 4 types of ores, mainly feldspar rubidium, and in order to save cost and improve resource utilization rate, an extraction process for extracting the feldspar rubidium by a chloridizing roasting method and the like is adopted; in the two-long granite and the modified biotite granite, the contents of feldspar rubidium and mica rubidium cannot be ignored, and an extraction process for simultaneously extracting the feldspar rubidium and the mica rubidium by adopting a salt roasting water leaching method and the like is adopted to improve the extraction efficiency of the rubidium; in the cloud rock, mica and rubidium account for over 96 percent, and an extraction process for mainly extracting mica and rubidium by an acid method and the like is adopted for saving cost, improving resource utilization rate and reducing energy consumption.

The minerals with rubidium in the sample are mica, potassium feldspar and sodium long, wherein the extractable rubidium is mainly potassium feldspar rubidium29.26%) and rubidium mica (>51.85%) sodium feldspar rubidium is not counted in this example because of its relatively small extraction. In the modified biotite granite sample, the grade of potassium feldspar rubidium is relatively close to that of mica rubidium. If the technology of mainly extracting mica rubidium by an acid method and the like is adopted, the feldspar rubidium cannot be effectively extracted; if a process of mainly extracting feldspar rubidium by a chloridizing roasting method or the like is adopted, the extraction effect of mica rubidium is not good. Therefore, the method is suitable for effectively extracting the feldspar rubidium and the mica rubidium by adopting a salt roasting water leaching method and the like.
For dressing by adopting a magnetic-gravity-flotation combined process applied to dressing and smelting experimental study of national treasures mountain rubidium ore, huangxiao and the like, the operation recovery rate of feldspar rubidium concentrate is 75.34 percent, and the operation recovery rate of mica rubidium concentrate is 87.68 percent. The extraction of rubidium elements from mica rubidium concentrate and feldspar rubidium concentrate is carried out by adopting a salt roasting water leaching method of Fu Xin in the summary of the extraction process of rubidium in silicate ore resources, the extraction rate of mica rubidium is more than 92%, and the leaching rate of potassium feldspar is at most 94%. For the convenience of calculation, the rubidium extraction rates of the mica concentrate and the feldspar concentrate are 93 percent. Then the Extraction Rate (ER) of feldspar rubidium by the development and utilization process is to be adopted 1 ) 70.07, mica rubidiumExtraction yield (ER) 2 ) 81.54%.
