Question

B. Give one word for each.
1. leaching a basalt rock.​

Answer 1

Explanation:

Basalt leaching with orthophosphoric acid is studied by the method of isothermal dissolution. The total degree of dissolution of basalt and degrees of extraction into solution of separate elements as a function of temperature (20, 100°C), acid concentration (5–40%), and liquid-to-solid ratio are determined. Through the control of leaching conditions, it is possible to vary the coefficient of acidity of the basalt charge, decreasing the content of separate components. The possibility, in principle, of using this process for the optimization of charge composition in the manufacture of basalt-fiber materials and cast stone products is shown.
