难浸金矿固化焙烧预处理工艺及其机理对含砷金精矿固砷焙烧工艺条件进行了研究。

STUDY ON PRETREATMENT OF FIXING ROASTING & ITS MECHANISM OF REFRACTORY GOLD ORES The condition of fixing arsenic roasting process has been investigated .

实验结果表明：较适宜的溶样条件为温度50℃，溶样时间为3h，混合溶剂与金的液固比为6∶1（体积比）；

The results of the experiment show that the optimum conditions ( the temperature is 50 ℃, lasted time is 3 hours , the volume ratio of mixed solution and aurum is 6 ∶ 1 ) are determined ;

目的研究金合金卡环固位力与卡环臂进入基牙倒凹深度间的关系。

Objective To study the relationship between the depth of abutment undercut and the retention of gold alloy clasp .

相同倒凹深度上，磨牙金合金卡环固位力比前磨牙大。

The retention of gold alloy clasp on the molar was greater than that on the premolar in the same condition of undercut .

结论在卡环弹性极限内，金合金卡环固位力与卡环臂进入基牙倒凹的深度成正比。

Conclusion Within the elastic limit of the material , the relation between the retention of gold alloy clasp and the depth of abutment undercut showed positive correlation .

金主要呈金&银固溶体系列的独立矿物产出，包括银金矿、自然金和金银矿。

Goldoccurs mainly as independent minerals of Au Ag solid solution series , including electrum andnative gold pyrite is the main ore mineral and has a close relationship with gold .
