地質(zhì)礦產(chǎn)行業(yè)應(yīng)用解決方案

时间:2023-11-06     

地質(zhì)礦產(chǎn)行業(yè)包括:地質(zhì)化探普查、礦山勘探、選礦、冶煉等環(huán)節(jié),X熒光分析可以適用于各個(gè)環(huán)節(jié),具有制樣簡單、分析速度快、精度高等特點(diǎn),可以替代傳統(tǒng)的化學(xué)分析方法,帶來巨大的經(jīng)濟(jì)效益,地質(zhì)礦產(chǎn)行業(yè)包括有色礦產(chǎn)(銅、鉛鋅等)及黑色礦產(chǎn)(鐵)兩個(gè)行業(yè)。

應(yīng)用解決方案:
鐵礦石分析:

ELITE 600儀器,鐵礦石、鐵精粉樣品的分析,主要關(guān)心是鐵的品位,其它雜質(zhì)元素也要進(jìn)行定量測量,需要進(jìn)行熔融樣品分析,因此采用高精度的ELITE 600 X熒光分析儀是首要選擇。

對(duì)簡單鐵礦山可以采用直接壓片方式進(jìn)行快速測定,對(duì)復(fù)雜來源的鐵礦石、鐵精粉可以采用熔片方式進(jìn)行精確測定。


鐵礦石的測量譜圖如下:                                                                                         Fe的工作曲線:

鎢礦樣品分析

一種是礦山、選廠的分析,特點(diǎn)是:礦物結(jié)構(gòu)相對(duì)簡單,但過程樣品種類較多,主要有:粗毛砂、細(xì)毛砂、細(xì)中礦、中礦、搖床精礦、細(xì)精礦、磁精礦、外銷鎢精礦、鉬精礦、鉍精礦、廢石等樣品,有十幾種樣品,一般要求分別進(jìn)行曲線標(biāo)定,工作量比較大。

另一種是鎢冶煉廠,特點(diǎn)是:只分析精礦,特別是鎢精礦,但來源比較復(fù)雜,有不同地區(qū)不同礦山,有白鎢、黑鎢兩種結(jié)構(gòu)的鎢精礦,黑鎢不含CaO或很少,不超過5%,白鎢含CaO較高,一般在10-25%之間。

ELITE 600儀器,鎢礦及鎢精粉樣品的分析,主要關(guān)心是鎢的品位,其它雜質(zhì)元素也要進(jìn)行定量測量,可以采用直接壓片分析, 采用高精度的ELITE 600 X熒光分析儀完全可以滿足分析要求。
