FLORES, Horacio R  y  TINTE, María de los Á. Comparative Cost Calculation in the Obtaining of Borate Concentrates. Inf. tecnol. [online]. 2008, vol.19, n.3, pp.3-6. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642008000300002.

This paper presents the similitude found between flow sheets, material balances and equipments employed in the concentration of borates, to obtain base refined borates and to obtain high added value borates. Spread sheet calculations are used to determine the production costs for different operating conditions and to analyze the opportunity and convenience of changing the final product, using the same process plant. A study case is considered in which 10 tn/hr of ulexite concentrate or the same amount of hydroboracite are produced. The cost per ton of B₂O₃ was 94.3 US dollars for the concentrated ulexite and 67.5 US dollars for concentrated hydroboracite. It is concluded that the proposed method is an useful tool for the economic analysis of the productive process considered in this study.
