应用泡沫浮选萃取法从排放水中回收钼

根据实验室的试验结果，推荐应用浮选萃取联合工艺从水溶液中回收Mo(Ⅵ）。这一工艺包括制取以钼酸铵形式的商品，和对所有的有机试剂作再生处理。萃取Mo(Ⅵ）的准备系统，应包括在反萃取胺和用NaOH使水溶液碱化到pH=12以后，通过添加水溶液以使煤油、壬醇和AHII捕收剂按规定的比例进行混合等作业。对在萃取器中获得的混合液进行相分离后，有机溶液可用作泡沫浮选萃取Mo(Ⅵ）的萃取剂，而水溶液则加入到原始溶液中。     

Zu Fragen der Ausbildung und Weiterbildung im österreichischen Bergbau

Training and continuous education is today for the management of a mineral producing operation more important than ever before. The focus of education today in the field of mineral producing industry has not only to be dedicated versus the needs of the industry but also versus the importance of the ever increasing need of societal acceptance of industrial operations. Therefore it is expected that graduates from mining schools not only have a good knowledge of technical and economical subjects but also a good background for the realisation of environmental and safety targets for the people at work and in the neighbourhood of an operation. A strong request to the education and training at university level is therefore not only to deliver a broad knowledge but also the formation of a basis which allows to obtain authority for functions as “safety expert”, “Mine rescuer”, “waste disposal expert” and others. In the text the contents of the BSc study program “Natural resources” are reviewed and the training and education for a “Natural Resources Manager” together with the required continuous education is discussed.     

Groundwater problems in surface coal mining in Scotland

The paper reviews the problems encountered with groundwater in surface mining in Scotland. The problems which occur at various stages of the mining process from initial exploration to mine planning and final restoration are referred to. Special consideration is given to mine drainage and pumping methods.     

Rheological Properties and Characteristics of Hydraulic Transportation and Heat-Mass Exchange of Coal-Water Fuels

The procedure is proposed for calculating the characteristics of flow and heat exchange of coal-water fuels as applied to the pipeline hydraulic transport and heat-mass exchange in the apparatus of ecologically clean combustion in the objects of power engineering.
