广西伴生银矿床的地质特征与综合开发     

梁有彬 《南方国土资源》1990,(2)

本文叙述广西伴生银矿床的类型,地质特征及其开发利用情况。该区除独立的银矿床外,伴生银矿床可划分为8种成因类型。与铅、锌锡有关的伴生银矿床的银金属储量占伴生银总量的89.55％全区大多数生产矿山伴生争回收率低,未能得到合理的利用。为了充分利用有色金属矿床中伴生银资源和增加白银储量,应加强生产矿山物质成分,赋存状态和分布规律的研究,开展独立银矿床的预测和勘查,提高矿石中伴生银的回收率和矿山地质的研究。  相似文献

Geochemical survey of thermal system in Northeast China and their geothermometric characters     

MohammedHazaea HUKe MohammedMattash CHENBing M.O.AI-JabaliAref MohammedAbdussalam 《东北亚地学研究》2004,7(2):181-184

The chemical composition of several thermal springs around Changbaishan area has been investigated. Cenozoic basaltic rocks are widely distributed in Northeast China and geothermal characteristics have been described. About one hundred hot springs exist around Changhaishan Volcano at the border between China and D.P.R.Korea with high temperature about 82~C. The pH values of the spring water range from 6.9 to 7.1 and the total flow rate is about 4.8 L/sec. The chemical composition of the thermal springs is sodium carbonate; the high-mineral contents of thermal water are believed to have medicinal properties. Bathhouses are already built along the hot springs to take the advantage of the supposed healing properties. The high quality of those hot springs is believed to be utilitized for mineral water. The chemical equilibrium temperatures were estimated at about 160℃ based on the Na-K-Ca geochemical thermometer.  相似文献
