The chemical compositions of chlorite, one of the most common clay minerals, are thought to have a close relationship with its formational environments such as geological conditions, temperature, chemistry of hydrothermal solution, etc. In this study two chlorite geothermometers were considered by using the chemical composition of chlorites from some hydrothermal ore deposits in Japan. The two chlorite geothermometers are the Cathelineau's thermometer giving an empirical temperature scale of chlorite formation in an active geothermal field, and the Walshe's thermometer giving a thermodynamic temperature scale based on exchange reactions of chlorite solid solutions. On the basis of a comparison of fluid inclusion geothermometry, it is concluded that the two geothermometers can be applied to different compositional types of hydrothermal chlorite. The Cathelineau's thermometer fits well for Mg-chlorite, and the Walshe's thermometer fits for Fe-chlorite, indicating that both two chlorite geothermometers can be used as exploration indicators for geothermal reservoirs and hydrothermal ore deposits. In addition, it must be emphasized that the impurities in the chlorite should be examined in applying the chlorite geothermometers to chlorites.","PeriodicalId":21719,"journal":{"name":"Shigen-to-sozai","volume":"3 1","pages":"694-699"},"PeriodicalIF":0.0,"publicationDate":"2008-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87282884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One is many collecting & sorting enterprises and processing & wholesale enterprises, which are usually small and medium-sized business. The other is nonferrous metal smelting & refining enterprises, which are usually big business. Recently legislative resource recycling system, which consists of Home Appliance Recycling Law, End-of-Life Vehicles Recycling Law, Law for Promotion of Effective Utilization of Resource and so on, has been also developed. But, in spite even in these circumstances, considerable amount of domestic occurrence scraps of copper has been exported to China, and a lot of used home appliances and used personal computers have been exported to foreign countries. Namely, it has become clear that the present resource recycling system could not circulate the resources sufficiently inside Japan.These problems were caused by rapidly increasing resource consumption of the world in these several years, which was originated by quick economic development of the Asian region, in especial in China. Tightness of worldwide resource demand has requested the advancement of creating new countermeasures and/or corresponding methods under the slogan of “conservation and effective utilization of resources” for a long time.This manuscript intoroduces these circumstances and suggested some solutions to the problems.","PeriodicalId":21719,"journal":{"name":"Shigen-to-sozai","volume":"122 1","pages":"779-783"},"PeriodicalIF":0.0,"publicationDate":"2007-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82674847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mining and smelting of lead, zinc and silver bearing ores from the original Hosokura Mine began over 1,200 years ago, but was terminated with the closure of the mine in 1987 and, since then, the production of recycled lead and the treatment of mine wastewater have been continued. The current company was reorganized in March, 2006. Although the capacity for monthly lead production based on a blast-furnace operation followed by electro-refining is around 2,000 t /month, a serious shortage of recycled batteries triggered technology development to accept lead dross and lead residue etc.also as low grade raw material in the summer of 2005. Another main operation of this company is the treatment of mine wastewater, 15 t /min on average, from the closed mine and the effluents from lead plants to meet the water quality standard against toxic elements including lead. Overcoming the lead-leakage problem at this plant in May, 2002, the thoroughly renewed and strengthened water-treating system with a big deep bed filtration facility at the final stage enables us to contribute to the environment improvement of this area and rebuild the tight, friendly correlation with the surroundings. Both the plants are operating under the company policies of environmental conservation, compliance and community involvement.","PeriodicalId":21719,"journal":{"name":"Shigen-to-sozai","volume":"18 1","pages":"719-722"},"PeriodicalIF":0.0,"publicationDate":"2007-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76883713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, global use of mineral resources have become huge. Rapidly growing China's appetite has a great impact. Therefore, it is the author's big concern over the following issues for sustainability of the world.Depletion of resources, progress of the domination by international resources majors, increasing dependence on resource-rich but politically unstable developing countries, resurgence of “resource nationalism”, beginning of world wide struggle for securing resources against possible shortage, serious environmental problems caused by massive mine development, frequent conflict between mining companies and local people, and escalating market prices.Just now, it can be said an era of “Resources Crisis”. However, in today's global economy, nation's economic security depends on access to adequate mineral resource supplies from a variety of international sources.Under these circumstances, it is strongly expected that (1): Japan should immediately act for resources security with firm diplomatic strategies (2): Japan should make its best efforts to achieve the world highest resource productivity (Material Intensity per Service unit = min.) for environmentally sustainable development of the world.Several suggestions to cope with resource crisis are made.","PeriodicalId":21719,"journal":{"name":"Shigen-to-sozai","volume":"31 3 1","pages":"564-572"},"PeriodicalIF":0.0,"publicationDate":"2006-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81161349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reaction time was 30 minutes. It was found that, during the hydrothermal treatment, the yield of solid phase decreased and the total organic carbon (TOC) of liquid phase increased as the biomass-mixing ratio increased. That means that the biomass was more decomposable than the coal. Besides, volatile matter in the material sample showed a higher decomposability, as compared with fixed carbon, and part of the decomposed volatile matter was considered to produce new aromatic compounds and carboxylic acids through repolymerization to fixed carbon. As a consequence, the gross calorific value of the solid phase of the hydrothermally treated mixture became higher with increasing biomass-mixing ratio on a dry basis. Considering ash content, the solid phase showed negligible change in gross calorific value, independent of the mixing ratio; it was ca. 7300 kcal/kg on a dry ash-free basis. In addition, it is worth mentioning that a five-hour run using a bench-scale continuous equipment was conducted successfully.","PeriodicalId":21719,"journal":{"name":"Shigen-to-sozai","volume":"1 1","pages":"522-527"},"PeriodicalIF":0.0,"publicationDate":"2006-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76577926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
