- (NH4)2CO3およびNH4OHを含む炭酸アンモニウム溶液に製鉄所で発生するZn含有発生物を溶解させ、その溶液中の不純物を金属Znの添加により低減した後に、当該溶液より炭酸亜鉛を晶析させる炭酸亜鉛の製造方法において、
炭酸アンモニウム溶液にZn含有発生物を溶解させる溶解工程を行う前に、実際の溶解に用いる炭酸アンモニウム溶液と同じ組成の炭酸アンモニウム溶液にZn含有発生物を試溶解した液を分析することにより、当該Zn含有発生物中の、炭酸アンモニウム溶液に容易に溶解するZn(以下「易溶性Zn」という。)の含有量を把握し、これに基づいて、当該Zn含有発生物からの易溶性Znの配合量が、当該炭酸アンモニウム溶液の組成により決まるZn溶解能力に対して80〜100質量%となるように、炭酸アンモニウム溶液に対するZn含有発生物の配合比率を決定し、溶解工程を行うことを特徴とする炭酸亜鉛の製造方法。
