Which of the following is not an ore of iron?
— Note: Iron formation consists of ore like siderite, magnetite, and hematite, with silica within the variety of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of ore are sometimes high-grade but are often mixed with an honest deal of silica, the full making an ore too lean to be used without concentration.
