The paper describes the properties of minerals at Qixiashan Pb-Zn-Mn ore deposit in Nanjing and introduces a new non-cyanide method for floating sulphide ores and preflotation of carbonous minerals, pyrite which have higher floatability. A discussion on some factors affecting the process is also given in the paper. It has been proved through the commercial tests that when using the said process, the grades of lead and zinc concentrates increased by 6.48%, 0.67% and their recoveries by 8.4%, 4.92%...

The paper describes the properties of minerals at Qixiashan Pb-Zn-Mn ore deposit in Nanjing and introduces a new non-cyanide method for floating sulphide ores and preflotation of carbonous minerals, pyrite which have higher floatability. A discussion on some factors affecting the process is also given in the paper. It has been proved through the commercial tests that when using the said process, the grades of lead and zinc concentrates increased by 6.48%, 0.67% and their recoveries by 8.4%, 4.92% respectively as compared with those obtained from the previous cyanide process. It is perfectly feasible in technology that for the low-grade Pb-Zn ore containing carbon and pyrite which has higher floatability, a selective flotation of lead can be performed without using cyanide. It, furthermore, is also of benefit to economy.

本文介绍了栖霞山铅锌锰矿的矿石特性,提出了浮选法预先浮出碳质矿物及可浮性好的黄铁矿等易浮矿物的无氰浮选工艺。论述了该工艺的试验室研究和工业试验结果。对于含有碳质矿物和易浮黄铁矿的低品位的铅锌矿石,完全不用氰化物进行优先选铅,技术可行,经济合理。

This paper comments on the geological features of various medium-and small size rich manganese ores and the favorable prospects. These rich Mn ore deposits occur predominently in weathered, marine sedimentary and strata-bound Pd-Zn-Fe mineralizations.

湖南锰矿资源丰富,但富锰矿床规模小,难选矿石多.主要矿床有风化型、海相沉积型和层控铅锌铁锰型矿床等三种类型.本文主要根据湖南富锰矿床分布特点,提出综合找矿方向.

The Huya type Fe—Mn ore deposits, an important type manganese deposit in Sichuan Province ,are mainly distributed in Songpan—Heishui region and occurred in the upper Bocigou Formation of Lower Triassic Series. The sedimentary facies in the late period of early Triassic Epoch may be divided into: external shelf microfacies, internal shelf microfacies, offshore bar microfacies,submarine bar microfacies and shallow seashelf transitional zone microfacies. The palaeogeographical framework are recognized...

The Huya type Fe—Mn ore deposits, an important type manganese deposit in Sichuan Province ,are mainly distributed in Songpan—Heishui region and occurred in the upper Bocigou Formation of Lower Triassic Series. The sedimentary facies in the late period of early Triassic Epoch may be divided into: external shelf microfacies, internal shelf microfacies, offshore bar microfacies,submarine bar microfacies and shallow seashelf transitional zone microfacies. The palaeogeographical framework are recognized as: Kang—Dian (Xikang Yunnan)palaeocontinet in south Sichuan,a NE—SW trending paloeo—island chain in Longmenshan area,and a palaeocontinent upheaved in Motianling area in Palaeozoic era. In the sea basin in Songpan—Heishui region,two submarine swells,(Jone—Jiaochang and Jone-Weigu)are occurred. The Huya shallow sea trough lies to the east of the Jone—Jiaochang swell,in the middle of these two submarine swells is the wabuliangzi submarine depression and to the west of the Jone—Weigu submarine swell is the Heishui semi—enclosed basin. The formation of the Huya type Fe—Mn deposits were strictly controlled by petrographical and palaeogeographical conditions.

四川省虎牙式铁锰矿床主要分布于松潘—黑水一带,赋存于下三叠统菠茨沟组上段地层中。虎牙式铁锰矿床是四川省重要的锰矿类型之一。早三叠世晚期的沉积相可划分为:外陆棚微相、内陆棚微相、远滨砂坝微相、水下砂坝微相和浅海陆棚过渡带微相。古地理格局:四川省南部是康滇古陆,龙门山地区存在一条北东—南西向分布的古岛链,摩天岭一带为古生代隆起的古陆。在黑水—松潘一带的海盆中,有卓尼—较场、卓尼—维古两个水下隆起。在卓尼—较场东侧为虎牙浅海槽;两个水下隆起之间是瓦布梁子水下洼地;卓尼—维古西侧是黑水半局限盆地。虎牙式铁锰矿床的形成严格受岩相—古地理条件的制约。
