Environmental
pollution is one of the most crucial issues of concern in all life fields and
is highly required to pay more attention to it in order to protect environment
and human been. Environmentally responsible and rentable metallurgical
industries put among their key objectives the development of utilization
schemes of all of its by-products. The recovery of metals by separation and
cementation in metallic forms is overviewed based on the fact that these metals
have higher electro-chemical potentials than zinc. Besides zinc, these sulphate
solutions contain impurities such as Cu, Cd, Co, Ni, As, Ge, Sb, Se, Te and Ag.
Based on the above data, it is evident that the selective recovery of these
metals from these solutions represent a significant economic added value, but
as well it must take into consideration and arsine as by-product of this
process that can be benefit and its effect in environment and employees’
health. In this point of view, in order to revive and improve operation
practices as per design capacity in the company is necessary to improve the
process condition and to avoid the releasing of the arsine in air.
