次生富集带

中国西部地区钙芒硝矿床发育次生富集带，形成可供工业利用的次生芒硝矿床。

There is a secondary enrichment zone of glauberite in the western part of China to have developed a number of usable glauberite deposits .

晚第三纪的表生淋积作用，使矿体上部近地表处形成次生富集带。

The supergene infiltration in Neogene pened resulted in the formation of a secondary enrichment zone in the upper part of the ore body near the surface .

本文对黄铁矿型铜矿次生富集带矿石在浮选过程中泡沫发粘，致使铜回收率大幅度下降的原因，进行了选矿矿物学的研究。

This paper describes the cause of the viscous froth produced in the flotation process of the secondary enrichment ore in a pyrite-type copper deposit .

按此公式计算出两个典型矿床氧化带金的淋失率、地表指示性边界品位、指示性平均品位以及半氧化一次生富集带金的富集率。

The leaching loss rate of gold in oxidation zone , its surface indicative cut-off grade , indicative average grade and enrichment factor for two typical deposits were calculated by using the formula derived .

在充分研究次生富集带含铜黄铁矿矿石特性的基础上，采用优先浮选铜矿物，粗精矿再磨精选工艺流程的闭路试验获较好选别指标。

After making a fully research on the characteristics of copper-carried pyrite in secondary enriched zone , better flotation indices can be obtained through a closed circuit test adopting preferential flotation of copper minerals and regrinding of rough concentrate and fine-dressing .

土状铜矿不存在次生硫化物富集带，铜次生富集于氧化带中，与经典的硫化矿床表生分带明显不同。

There 's no secondary copper sulfide enrichment zone . The secondary copper enrichment subzone locates in the oxidation zone and this is obviously different from supergene zones of typical sulfide deposits .
