Abstract

Cette invention a trait à un procédé de production de nitrate de potassium par relargage à partir d'une solution aqueuse renfermant les ions K?+, C-, M++ et NO-¿3, M++ représentant Ca++ et/ou M++. Ce procédé consiste, (a), à dissoudre au moins un minéral choisi dans le groupe constitué par du carbonate de calcium, du carbonate de magnésium, de l'oxyde de magnésium, de l'oxyde de calcium, de l'hydroxyde de calcium, de l'hydroxyde de magnésium et par de la dolomite, dans de l'oxyde nitrique aqueux sous des quantités qui, du point de vue stoechiométrique, sont sensiblement équivalentes à la quantité des ions nitrate présents dans la solution, ou bien à dissoudre au moins un minéral choisi dans le groupe constitué par du nitrate de calcium et du nitrate de magnésium, dans de l'eau, (b), à dissoudre au moins une source de chlorure de potassium dans la solution obtenue lors de la phase (a) et ce, à une température supérieure à 40 °C, la quantité de la source étant calculée de manière à obtenir un rapport sensiblement stoechiométrique entre les ions de potassium et de nitrate. Cette source est choisie dans le groupe constitué par du KCl, de la carnallite, de la sylvinite ainsi que par un mélange de KCl et de MgC1¿2?, NaC1, CaC12 ou par leur combinaison et, (c), à refroidir la solution obtenue lors de la phase (b) afin d'obtenir un précipité de nitrate de potassium.
