Optimization of the operating parameters in gold electro-refining
Firstly, a high gold content of the anode (more than 95 %) is needed, which requires pre-refining with other refining methods (Miller process) associated with gold Abstract. Analytical methods and techniques for the determination of gold contents are employed in the exploration and evaluation of gold deposits, grade control in primary Gold Analysis: From Fire Assay to Spectroscopy — A Review

The Middle East has witnessed major geopolitical shifts since 2011 that range from the growing influence of the Gulf states, the pivot to Africa of many of the region’s countries and the new dynamics of global penetration, to the proliferation of regional cleavages and intra-state conflicts, as well as more volatile alliances and rivalries.Jewellery demand in the UAE also outstripped those in other Middle East countries, where total demand reached 27.5 tonnes. Regional demand Across the Middle East, gold demand went up by 15% year-on-year to 190.4 tonnes, higher than in the Americas (187.8 tonnes), Europe (70.6 tonnes) and other Asian countries, except major markets like Greater UAE sold the most gold in Middle East in 2022 ZAWYA

Gold prices surge on Middle East tensions Article ING Think
Gold eyes more gains. We have revised our fourth quarter forecast upwards to $1,950/oz, raising our 2023 average to $1,937/oz given the outbreak of the Israel-Hamas conflict and the risk of tensions escalating in the Middle East. However, we still believe the Fed’s higher-for-longer narrative will keep the rally in check.For Europe, this challenge is reflected in the European Green Deal, which puts renewable hydrogen produced by electrolysis high on the political agenda. The European Hydrogen Strategy sets a target for 6 GW installed electrolyser capacity by 2024, and 2x40 GW by 2030 (40 GW in Europe and 40 GW in neighboring countries) European Research Institutions present Joint Action Plan to
