Nowadays, the export volume of copper concentrate from the Republic of Armenia equals more than 500 thousand tons per year. This extent fully satisfies the minimum requirements for constructing a copper smelter in our country. Calculations show that the copper production capacity of the Republic of Armenia is estimated more than 120 thousand tons per year. Although it is considered to be a modest result in the context of copper mining scale worldwide, it is of significant importance for our country. The production and export of pure copper will contribute to the flow of currencies into our country. Meanwhile, it will enable to construct and exploit a cable factory, which, in turn, will create favorable grounds for new working places and for the rise of overall economic activation. The necessity for constructing a copper smelter has also been stated by the government of the Republic of Armenia. One of the concerns remains the realization of sulfuric acid extracted in the process of copper production. A solution could be transporting it to the port by railway through the area of Georgia. Still, according to some viewpoints, it is possible to recycle sulfuric acid on the spot and convert to fertilizers, varnish, paint, clay etc. The paper takes into focus the possibilities of constructing a copper smelter in the Republic of Armenia demonstrating the efficiency of investments and their buyback deadlines on current copper price conditions.
