An iron ore was found to contain 92.0% pyrite (fool's gold). Pyrite …
Since,iron ore contain 92 percent pyrite. So, 50.8 grams of iron ore contain 50.8 x 0.92 = 46.736 g pyrite. from this we need to find 46.5 percent of the iron content in the 92 percent pyrite section we found at the start.46.736 x 0.465 = 21.73224 g. Then add this answer to the 8 percent of iron ore. 21.73224 g +4.064 = 25.79624 g of iron ore ...Web

An Introduction to the Chemistry of Metal Extraction
As you will see if you read the page about titanium extraction, this is the only way of producing high purity metal. TiCl4 + 4Na → Ti + 4NaCl T i C l 4 + 4 N a → T i + 4 N a C l. The more reactive metal sodium releases electrons easily as it forms its ions: 4Na → 4Na+ + 4e− 4 N a → 4 N a + + 4 e −. These electrons are used to reduce ...Web
