Calcium silicate board prepared from ferronickel acid leaching residues and preparation method of calcium silicate board
The invention discloses a calcium silicate board prepared from ferronickel acid leaching residues. The calcium silicate board is prepared from the ferronickel acid leaching residues, a calcium raw material and reinforced fibers, based on 100% of the total mass of the ferronickel acid leaching residues and the calcium raw material, the ferronickel acid leaching residues account for 50-80% by mass, and the calcium raw material accounts for 20-50% by mass; the ferronickel acid leaching residues are obtained by carrying out pretreatment including acid solution soaking and solid-liquid separation on ferronickel residues. The invention discloses a preparation method of the calcium silicate board prepared from the ferronickel acid leaching residues. The calcium silicate board is prepared by matching the ferronickel acid leaching residues with the calcium raw material and the reinforced fibers, so that a large amount of ferronickel residues can be consumed, and reduction and high-value utilization of the ferronickel residues are realized.
本发明公开一种镍铁酸浸渣的硅酸钙板，包括镍铁酸浸渣、钙质原料、增强纤维；且按所述镍铁酸浸渣和所述钙质原料的质量总和为100％计，所述镍铁酸浸渣质量占50～80％，所述钙质原料质量占20～50％；所述的镍铁酸浸渣为镍铁渣经过包括酸溶液浸泡和固液分离的预处理所得。本发明公开一种上述镍铁酸浸渣的硅酸钙板的制备方法。本发明利用镍铁酸浸渣搭配钙质原料和增强纤维制备出硅酸钙板，能消耗掉大量的镍铁渣，实现了镍铁渣的减量化和高值化利用。
