Jamaica has developed a new strategy designed to allow it to expand its bauxite and alumina production, to diversify both its markets and its sources of investment and, to move downstream into the production of aluminium and semi-finished products. Some benefits of this new strategy are already evident, several bauxite mines are being expanded, alumina plants are being re-opened while others are adding additional capacity, and the countries of Europe, Asia and North America are showing renewed interest in investing in Jamaica. With its new strategy, Jamaica intends to participate more fully in the world economy. 相似文献

Along with the gradually increasing yield of the residues, appropriate management and treatment of the residues have become an urgent environmental protection problem. This work investigated the preparation of a glass–ceramic from a mixture of bottom ash and fly ash by petrurgic method. The nucleation and crystallization kinetics of the new glass–ceramic can be obtained by melting the mixture of 80% bottom ash and 20% fly ash at 950 °C, which was then cooled in the furnace for 1 h. Major minerals forming in the glass–ceramics mainly are gehlenite (Ca2Al2SiO7) & akermanite (Ca2MgSiO7) and wollastonite (CaSiO3). In addition, regarding chemical/mechanical properties, the chemical resistance showing durability, and the leaching concentration of heavy metals confirmed the possibility of engineering and construction applications of the most superior glass–ceramic product. Finally, petrurgic method of a mixture of bottom ash and fly ash at 950 °C represents a simple, inexpensive, and energy saving method compared with the conventional heat treatment. 相似文献
