Determine the dosage of the medication. Let's say the appropriate dosage of the active substance is 2 mg/kg of body weight. Weigh yourself. Let's assume you weigh 80 kg. Multiply these two values to get the dose of medication in mg: 2*80 = 160 mg. You need to take 160 mg of active substance. What if your medication is liquid?

Whilst some studies show that the ore grade is decreasing over time [6,7,8,9], other studies state that the declining ore grades must neither be interpreted as a sign of depletion nor as an indicator of resource availability [10,11].This is because changes in ore grade can be attributed to other factors such as innovation and improvements in extractive technologies, extending the life of older

Iron ore - Wikipedia

Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces.Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel.
