The general formula for after-tax cost of debt then is pretax cost of debt x (100 percent - tax rate) The company will retain the non-taxed portion of the debt while the government taxes the taxable portion of the debt For example a company borrows $10 000 at a rate of 8 percent interest The pre-tax cost of debt is then 8 percent

Using column flotation it is possible to simplify the process by replacing two to three cleaner stages and associated transfer pumps with a single column producing final concentrate Reagent savings depend on the nature of the ore being treated and the reagent scheme being utilized
