On average, a woman has her period from three to seven days and the average woman menstruates from age 13 until age 51. That means the average woman endures some 456 total periods over 38 years, or roughly 2,280 days with her period -- 6.25 years of her life. Midol. You can only take up to six caplets a day, and cramps usually persist for two days. There are 40 caplets per package of Midol, which costs $8.99 at Walgreens. 12 caplets x 456 periods = 5,472 caplets. At 40 caplets per container, that's 136.8 Midol purchases x $8.99 = $1,229.83.
The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides (Table 1). Chalcocite (Cu2S) is the main copper sulphide mineral mined at bioleaching operations. Some of the chalcocite heap operations began as oxide (chemical) leach operations and were converted to bioleach (oxidative) operations by heap aeration and/or inoculation, when the oxidised ore was depleted.
Hyponyms (each of the following is a kind of iron ore): goethite; gothite (a red or yellow or brown mineral; an oxide of iron that is a common constituent of rust) chamosite (a greenish grey or black silicate of iron and aluminum) taconite (a variety of chert containing magnetite and hematite; mined as a low-grade iron ore) haematite; hematite (the principal form of iron ore; consists of ferric oxide in crystalline form; occurs in a red earthy form) lepidocrocite (a red to reddish brown mineral consisting of iron oxide hydroxide; often found in iron ores together with goethite) limonite (a widely occurring iron oxide ore; a mixture of goethite and hematite and lepidocrocite) magnetic iron-ore; magnetite (an oxide of iron that is strongly attracted by magnets)
