Caracterização mineralógica, química e solubilização do potássio de glauconita modificada

Demand for potassium in Brazil is large and is constantly increasing, but only about 5% of all consumed potassium is produced in the country. This low domestic production implies high rate of potassium imports, leaving the country vulnerable in the event of any difficulty to import this product and currency fluctuations. The modified glauconite is a rock that has a high potential for potassium exploration, found in Minas Gerais state, its extraction is relatively cheap and the prospected rock volume is high. The difficulty for its use as a direct source of potassium is in its low solubility. Thus, the objective of this study was to perform a chemical and mineralogical characterization of the modified glauconite and evaluate the effectiveness of techniques and treatments in the potassium solubilization contained in the rock. For this study, it was used characterization techniques such as X-ray diffraction, scanning electron microscopy, diffraction by Synchrotron Light and chemical analysis of high and low power of potassium extraction. Also granulometric testing and thermal treatments with different forms of calcination were carried out. Overall, it was found that the modified glauconite is a compound of minerals, of the mica groups K-feldspar and quartz and calcination substantially alter the crystal structure of these minerals, increasing the potassium availability. While the natural solubility of glauconite modified be very low, rock calcination added with high fluxes of calcium and low magnesium content at 1200 °C led to potassium solubility increase in order of 100 times compared to that observed in the glauconite natural modified.

Domestic Workers in Jamaica

This paper addresses how and why domestic workers in Jamaica are disenfranchised, with particular emphasis on the law’s inability to combat their exploitation in the labour force. My starting point is an online newspaper article entitled “Coping as a Domestic Helper”, which was based on a study investigating the living standard and coping strategies of minimum wage earners. In Jamaica domestic workers fall into three main categories - the residential worker, the non-residential weekly worker and the daily worker. Domestic workers are undervalued and their plight is especially grievous because they are characterized by a number of features that combine to have an exponentially negative effect on their social worth.

Opportunities and risks associated with the advent of digital currency in the Caribbean

This report examines the usage of digital currency technology in the Caribbean subregion with a view to drawing attention to the opportunities and risks associated with this new phenomenon. It discusses the broader context of an emerging activity at the global level and considers how this technology could address subregional deficiencies in the electronic payment infrastructure. The report also discusses mobile money solutions, and the relationship of that technology to digital currency.
