Tantalum Stock Price | TIC
To calculate the value of a tantalum mineral, the main principle is that only the quantity of Ta 2 O 5 contained is paid for, not the whole bulk of material. Basically the weight of material is multiplied by the percentage grade e.g. 30%, then multiplied by the pricing rate of X$/lb Ta 2 O 5. Note that while our industry statistics have moved ...
