Development of Technology of the Waste Water Purification Containing Toxic Ions of Heavy Metals

Description

The main purpose of the project is the purification of the waters polluted by ions of heavy metals. These waters are similar to quarry waters polymetallic deposit or waters – solutions of underground leaching of poor polymetallic ores. For this purpose it has been investigating new electrochemical ways and approaches of hydrometallurgy which simultaneously enable to give to the form of commodity to the components extracted quarry waters. Their realization in many cases would pay back costs on purification of waters before they become ecologically harmless formations. These waters can be used as pure secondary waters or can descend in pools of the rivers.

In 2003 in the Institute of Inorganic Chemistry and Electrochemistry of the Georgian Academy of Sciences it has been started researches on purification of quarry waters of the Madneuli mountain-concentrating plant of Georgia. Debit quarry waters make (8-10 )*105 m3 annually; composition (kg/m3 ): 0,8-1,2 Cu; 0,4-0,6Zn; 0,2-1,2Fe; pH=1,5-2.5. Quarry waters contain also other colorful and rare elements.

Innovative Aspect and Main Advantages

  • New electrochemical reactor has been developed, allowing to selectively extracting from 94-97 % of copper in the form of a metal powder from quarry waters.
  • Enables of complex processing of quarry waters with extraction of copper, zinc and other metals in the form of different commercial products.

Areas of Application

The offered process can be utilized for clearing quarry and industrial sewages, and solutions of an underground leaching.

Stage of Development

Design of electrochemical reactor is covered by Georgian Patent #2004 3369.
