Abstract
PROCESSO DE PRODUÇçO DE FERTILIZANTE DE POTÁSSIO A PARTIR DE NEFELINA SIENITO. A presente invenção diz respeito a um processo de obtenção de um termofertilizante de potássio, a partir de uma rocha denominada nefelina siento constituída de feldspatos alcalinos, sem quartzo. A técnica conduz á produção industrial e consiste na cominuição do minério a uma granulometria abaixo de 3,32 mm, seguido de ustulação salina em fornos, com a adição de cloretos de metais alcalino-terrosos para a quebra da molécula de feldspato, seguido de resfriamento à temperatura ambiente, de forma a disponibilizar o nutriente potássio para as plantas. Esta disponibilidade do potássio no produto é avaliada mediante ouso de xtratores do tipo: água, ácido cítrico, ácido nítrico e solução mellich. O termofertilizante de potássio obtido destina-se à cultura de liberação lenta do K, para uso na agricultura de pequenas propriedades.POTASSIUM FERTILIZER PROCESS FROM NEFELINA SIENITO. The present invention relates to a process for obtaining a potassium thermofertilizer from a rock called nepheline siento consisting of alkaline feldspars without quartz. The technique leads to industrial production and consists of the comminution of the ore to a particle size below 3.32 mm, followed by salt roasting in furnaces, with the addition of alkaline earth chloride to break the feldspar molecule, followed by cooling. at room temperature to make potassium nutrient available to plants. This potassium availability in the product is evaluated by the use of water, citric acid, nitric acid and mellich solution. The obtained potassium thermofertilizer is intended for the slow release K crop for use in smallholder agriculture.
