亚硫酸对紫硫镍铁矿浮选作用的研究

A Study of the Action of Sulphurous Acid with Violarite Flotation

研究结果表明，温度对黄镍铁矿阳极溶解过程影响显著。

It was shown that the dissolution is significantly influenced by temperature .

紫硫镍铁矿化学成分波动大，易氧化，易过粉碎，因此可浮性十分复杂。

Violarite has high volatility and is easy to be oxidized and overgrinded , so its floation nature is quite complicated .

在伟晶岩接触带，硫化物成分变为黄铜矿、针镍矿、黄铁矿及硫镍铁矿，伴生有磁铁矿和赤铁矿。福建海岸潮间带与水下沉积物粘土矿物分布

At pegmatite contacts the composition changes to chalcopyrite , millerite , pyrite , and violarite accompanied by magnetite and hematite . DISTRIBUTION OF CLAY MINERALS IN INTERTIDAL ZONE AND UNDERWATER SEDIMENT ALONG FUJIAN COAST

为了吸纳每年数以百万计流入城市的农村人口，中国进行了城市改造和新城市的建设，这转化为对资源的巨大需求，推高了铜、镍和铁矿石等大宗商品的全球价格。

The reconstruction of its cities and the building of new ones to absorb millions of rural migrants each year has translated into a huge demand for resources , lifting global prices for commodities such as copper , nickel and iron ore.

此法已用于测定钛铁合金、钛镍合金和钛铁矿中钛的含量，结果满意。

This method has been used for determination of titanium in ferro titanium alloy , titanium nickel alloy and titanium bearing iron ore with a satisfied result .
