Broadband frequency-domain electromagnetic sensors can be used not only to detect but also to characterize and identify a particular mineral deposit based on its spectral response. The concept is similar to identifying a particular landmine based on its unique spectral response, which is known as Electromagnetic Induction Spectroscopy (EMIS). Recent advances in single-coil, broadband sensors ha...

The goal of this paper is to improve our understanding of the costs and benefits of explicit deposit insurance. To this end, we compare the opportunity-cost value of deposit insurance services for a large sample of banks drawn from countries with or without explicit deposit insurance. After correcting for certain bankand country-specific factors, we find that the existence of explicit deposit i...

background: this research studied the feasibility of a simple method for extracting gold from central processing units (cpus) of computer circuit boards without solvent. methods: ceramic and composite cpus of computer circuit boards were used. gold was extracted using a hydrometallurgical method in six stages: grinding of cpus, leaching in nitric acid, leaching in aqua regia, removing the exces...

The influence of [Fe]-hydrogenase from Clostridium acetobutylicum was studied on the anaerobic corrosion of mild steel. Two short-circuited mild steel electrodes were exposed to the same solution and hydrogenase was retained on the surface of only one electrode thanks to a dialysis membrane. The galvanic current and the electrode potential were measured as a function of time in order to monitor...

This article describes the geology and industrial mineral potential of corundum, pyrophyllite and andaluite at the Empress deposit in the Taseko Lakes area (Figure 1). The Empress is a copper-goldmolybdenum porphyry deposit located 225 kilometres north of Vancouver and 50 kilometres northwest of Goldbridge and the Bralorne mining camp. Fine-grained corundum, in association with andalusite-pyrop...

This paper characterizes the optimal level of deposit insurance (DI) when bank runs are possible. In a wide variety of environments, the optimal level of DI only depends on three sufficient statistics: the sensitivity of the likelihood of bank failure with respect to the level of DI, the utility loss caused by bank failure (which is a function of the drop in depositors’ consumption) and the exp...

Southern Indian states are endowed with rich gem mineral wealth. High potential region for the occurrence of gem deposits appear to be the Precambrian region in the Eastern Ghats. Gemstones which are of mineral origin are found largely in metamorphic terrain. Salem district which is primarily enclosed by high grade metamorphic rocks is the study area. This study addresses field investigation an...
