Abstract
Wolframite and scheelite are important tungsten-carrying minerals in tungsten deposits.In this paper,in-situ laser Raman spectra analysis was carried out to study the effects of Mn and Mo elements on the structure of wolframite and scheelite.The results show:Tungsten-manganese ore appears in Raman activity peak of 882 cm-1,773 cm-1,696 cm-1,695 cm-1,544 cm-1,540 cm-1,394 cm-1,323 cm-1,325 cm-1,256 cm-1,204 cm-1,202 cm-1 and 126cm-1.Among them,the peaks at 540 cm-1 and 544 cm-1 are unique to the tungsten-manganese ore,and it is speculated that they may be the characteristic peaks to identify the tungsten-manganese ore,and the appearance of the characteristic peaks may be related to the high Mn content in the mineral.The Raman spectra of ordinary scheelite are 112 cm-1,207 cm-1,328 cm-1,366 cm-1,397 cm-1,429 cm-1,637 cm-1,692 cm-1,795 cm-1,834 cm-1,906 cm-1,1108 cm-1 and 1185 cm-1;The Raman spectra of Mo-scheelite are 1183 cm-1,1110 cm-1,913 cm-1,878 cm-1,839 cm-1,792 cm-1,692 cm-1,636 cm-1,392 cm-1,324 cm-1,202 cm-1 and 106 cm-1.Among them,the peaks at 1108 cm-1 and 1113 cm-1 may be the main characteristic peaks for identifying molybdenum-tungsten ore,and the addition of Mo element may also shift partial Raman displacement in the scheite.关键词
