In this paper, different leaching procedures were used for the chondrules and chondrule fragments of Semarkona, and the U-Th-Pb compositions of leachates and residues were analyzed by TIMS method. The residues normally give higher 206Pb/204Pb ratio, suggesting higher radiogenic Pb compositions. These residues form a Pb-Pb isochron, and give an age of (4566.9±5.8) Ma with MSWD of 26, consistent to the weighted average age of 207Pb/206Pb model ages.
在本文中,对Semarkona中球粒用不同的化学浸洗流程,并测定浸洗溶液和残渣中U-Th-Pb同位素组成,其中浸洗后的残渣均给出相对较高的206Pb/204Pb比值,表明其中含有较多的放射成因Pb同位素组成,这此残渣构成Pb-Pb等时线,给出年龄为(4566.9±5.8)Ma,MSWD=26,与207Pb/206Pb模式年龄在误差范围内一致。

Through the processes of grinding bastnaesite ore concentrate, mixing the ore powder with NaCO3 in the ratio of 1 to 0.1-0.4, roasting the mixture at 400-800 deg.c for 1-6 hr, elution of the roasted sand with hot water to obtain NaF, drying filtered drag after eluting NaF and mixing the dried drag with ammonium chloride, roasting the mixture at 300-600 deg.c for 1-3 hr, hot water soaking to obtain rare earth chloride solution, extraction with 20% kerosine solution of naphthenic acid, and hydrochloric acid counter extraction to obtain rare earth chloride product.
本发明涉及一种氯化铵法从氟碳铈精矿提取氯化稀土的方法,首先将氟碳铈原精矿磨细,并与NaCO 3 混合,其比例为原矿∶NaCO 3 =1∶0.1~0.4,混合均匀后在400℃~800℃焙烧1~6小时,焙砂用热水洗出NaF,洗出NaF的滤渣干燥后与氯化铵混合,于300℃~600℃焙烧1~3小时,再用热水浸取得到氯化稀土溶液,用20%的环烷酸煤油液萃取,再采用盐酸反萃得到氯化稀土产品。
