It is established that high quality gold is observed in the following mineral association: oxide mineralization; transition zone mineralization; sulfide mineralization. The high-grade gold observed in the following mineral association: barite-hematite-quartz-kaoline; hematite-quartz-kaoline; barite-sulfide-quartz. The low-grade gold observed in the following mineral association: disseminated pyrite; stock-stockwork pyrite; disseminated and veinlets covellite-pyrite (+/- turquoise) mineral associations. Deposit alteration signature has characteristics which suggest the current outcrop level may be near the top of a mineralized, gold-bearing high sulfidation epithermal (HSE) system. The gold mineralization at the deposit is interpreted as forming in shallow high sulfidation epithermal systems. The mineralization has been noted to occur in two different styles: well-confined hydrothermal breccias; associated with pyrite stock-stockwork. Most of the deposit material and current estimates are formed within the barite-hematite-quartz-kaoline mineralization in the secondary quartzite rocks. The main brecciation and stockwork are hosted within secondary quartzite, massive silicified andesite rocks.","PeriodicalId":434464,"journal":{"name":"Insights in Mining Science & Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130394189","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}

While there are clearly significant benefits to innovative teaching methods, there is a need for caution too in our fast-paced digital world where students have an extensive amount of visual information to hand throughout the day and night. Selflessness is also a factor when trying to innovate and innovation is not carrying a single idea to a predetermined destination and at some point, innovation must be inclusive. The Catholic University Institute of Buea (CUIB) as a professional university has taken the bold step to be the premier game changer and leader in entrepreneurial education in Cameroon and one thing is certain, that entrepreneurialism does not mean a compromise of traditional academic values. On the contrary, it not only fosters it but elevates it since it requires higher order thinking skills such as problem solving; creativity, critical thinking, and thinking for understanding and transfer. CUIB do not only teach students the tasks and practices of business (Heart of Business) but also help them to develop a moral compass(soul of Business) that will enable them to find the right solutions even when in uncharted territory with a growth mind-set.","PeriodicalId":434464,"journal":{"name":"Insights in Mining Science & Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129669042","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}

Natural resource exploitation is accelerating in the face of resource decline, while at the same time people are generating ever-growing fluxes of wastes and pollutants [1]. WEEE can be considered as a source of various metallic and nonmetallic components including critical or strategic materials for the development of new high technologies. Considering the ever-present possibility of depletion of non-renewable resources, the economic benefits of recovering valuable metals from the recycling of WEEE are potentially important in the coming decades. Metal ores stem from non-renewable resource stocks; and predictions as to how long metal world reserves will last depend mainly on economic growth, price trends and technological development [2,3]. The circular economy assumes that it is important to reuse consumer goods as well as efficiently and profitably extract valuable inputs from discarded materials such as electronic waste while mitigating environmental impacts over decades for those same wastes [4,5]. In developed and developing countries, the correlation between WEEE generation and its GDP is clear [6] as well as this correlation was also observed for South American countries [7]. Circular supply chains cannot circulate 100% of resources and hence new resource inputs from the natural environment will remain necessary. Moreover, a transition towards a circular economy requires innovative technologies for WEEE recovery and recycling practices to be sustainably managed.","PeriodicalId":434464,"journal":{"name":"Insights in Mining Science & Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127036551","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}

Presented here is a method for multiple simultaneous extraction of multiple metals and metalloids from regolith. Two patented approaches are described which can operate on a planetary surface, or in the microgravity environment of orbit. This approach to isotope separation applies to regolith fines but is advantageously applied to the effluent of a patented oxygen extraction method. In this way, a plurality of valuable raw materials can be obtained with a single system, suitable for operation on the Moon or at the surface of an asteroid. Silicon is of interest for studies of purity due to its importance in photovoltaics. A silicon-aluminum aerospace alloy can be produced directly, called Silumin, which has value in construction of habitats and space craft in space. Silicon can also be combined with carbon to form the wide-bandgap semiconductor SiC from which high-power and radiation-tolerant power transistors can be fabricated. Furthermore, this method lends itself to additive manufacturing whereby specific shapes of purified metals can be formed directly from the plasma extraction process.","PeriodicalId":434464,"journal":{"name":"Insights in Mining Science & Technology","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133075748","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}
