摘要

提出了一种从铜厂(PJSC MMC«Norilsk Nickel»极地分公司)的工业废气净化厂和铜电解车间的倾倒废物模拟器中去除镍的新方法。该方法基于用NOХ、HNO3或NH3蒸气气相处理废物，然后将Ni盐溶解在水中。研究发现，采用含有HNO3(蒸汽)、NOX和H2O(蒸汽)的硝化介质，可以有效地浸出模拟矿浆体积中的镍。该方法的一个可能的缺点是同时浸出相当数量的钙和硫。

Removal of nickel from nickel production pulp simulators during gas-phase conversion

A new approach to Ni removal from simulators of dump waste product of the industrial waste purification of the wet gas-cleaning plant and the copper electrolysis workshop at the Copper Plant (Polar branch PJSC MMC «Norilsk Nickel») is proposed. The method is based on gas-phase treatment of waste product with NOХ, HNO3, or NH3 vapors, followed by dissolution of Ni salt in water. It has been found out that using nitrating media, containing HNO3 (vapor), NOX and H2O (vapor), allowed us to perform the effective leaching of nickel from the pulp simulator volume. A possible disadvantage of the method is a simultaneous leaching of considerable amounts of calcium and sulfur.
