How to Convert Kilowatts to Amps. It is possible to convert kilowatts (kW) to amps using the Watt's Law power formula.The power formula states that current = power ÷ voltage.. To adapt the power formula to using kilowatts, first start by converting kilowatts to watts, which can be done by multiplying the power in kilowatts by 1,000 to get the number of watts.
The quartz microflotation tests were conducted at different pH conditions, various collector concentrations, and in the presence and absence of starch, a common depressant for iron minerals. The results indicated that in the absence of depressant, the maximum quartz floatability was achieved at pH corresponding to the collector's pK a .
