Antimony is found naturally in a number of minerals
VIDEO ANSWER: For this problem, we have 500 kilograms of stibnite, which is 59 .8 % antimony sulfide. So let's go ahead and figure out the 59 .8 % of 500 kilograms. We'll simply take 500 times 0 .598. 0 .598 is 299 kilograms. So we're actually

Focus on: Antimony, an Obscure but Vital Critical Mineral
The extraction of antimony involves both underground and surface mining methods, depending on the ore deposit's characteristics. After extraction, the ore undergoes crushing and flotation processes to concentrate the antimony content. The concentrate then goes through a smelting process to produce antimony metal or antimony oxide.
