黄铁矿石

含金黄铁矿石英脉矿石的浮选特征

Flotation Characteristics of Gold Containing Pyrite-Quartz Veins

金矿成矿主要经历黄铁矿石英金、石英金属硫化物金、石英碳酸盐金三个阶段。成矿物质主要来源于中泥盆统北塔山组含金建造。

The ore deposit underwent mainly three stages : pyrite-quartz-gold stage , metal-sulfide-gold stage and quartz-carbonate-gold .

建议选择可靠的石子供货商；在碎石加工前认真剔除黄铁矿石；

It is preferable to select reliable aggregate supplier , carefully pick away pyrite before processing gravel .

砷是西部孟加拉国的黄铁矿石层具有的天然元素之一。

Arsenic is a natural substance in the pyrite bedrock underlying most of the ground area in West Bengal .

北秦岭天水一带发现的金矿点，按成矿类型可划分为黄铁矿石英脉型、蚀变岩型和多金属硫化物型金矿。

According to mineralizing types , the gold fields found in north Qinling and Tianshui regions can be divided into pyrite quartz vein type , altered rock type and multimetal sulfide type .

陆丰黄铁矿床的原生矿石中普遍含金，含量0.3g／t以上者产于－100m标高以上。

The unweathered ores of the Lufeng pyrite deposit in Guangdong generally contain gold associations of which those grading more than 0.3 g / t occur above the - 100 m level .
