Processing mineralogy feature in the granite - pegmatite pattern tantalite - columbite ore

花岗伟晶岩型 铌 钽矿石的工艺矿物学研究

Laser micro-Raman probe analysis has been used to distinguish structurally this mineral species from isomorphic tapiolite . The result shows that the Ag Raman peak at 880 cm-1 is remarkable for tantalite .

用激光显微拉曼探针对 钽 铁矿进行的研究显示，位于880cm~（-1）的Ag拉曼特征峰非常显著。

Discovery of tantalite in the Suzhou granite and its geological significance

苏州花岗岩中 钽 铁矿的发现及其地质意义

The high density well crystallized ceramic strontium bismuth tantalite target was manufactured by reaction sintering of mixing SrCO 3 Bi 2O 3 and Ta 2O 5 powders . The calcination and sinter temperatures were 900 ￣ 1 000 ℃ and 1 000 ￣ 1 400 ℃ respectively .

高致密、结晶好的 钽 酸锶铋陶瓷靶由SrCO3、Bi2O3和Ta2O5粉末混合、预烧、压模和烧结而成，预烧和烧结温度范围分别为900～1000℃和1000～1400℃。

A hard gray lustrous metallic element that is highly corrosion-resistant ; occurs in niobite and fergusonite and tantalite .

一种坚硬有光泽的灰色金属元素，抗腐蚀性极强，见于铌铁矿、褐钇铌矿和 钽铁矿中。

There is high tantalite grade for certain large scale granite-pegmatite pattern tantalite-columbite mine in our country .
