The frothing agent causes the hydrophobic minerals to form bubbles, which rise to the surface of the slurry and can be skimmed off. The hydrophilic minerals remain in the slurry and are discarded.<\/p>\n<p>Chalcopyrite is a copper sulfide mineral that is often found in ores with other metals, such as gold and silver. It is a major source of copper, and is also used in the production of sulfuric acid.<\/p>\n<p>The froth flotation process is very effective in separating chalcopyrite from other minerals in the ore. The process is also relatively simple and inexpensive, which makes it a popular choice for the mining industry.<\/p>\n<p>The other options are incorrect because they are not hydrophobic minerals. Calamine is a zinc carbonate mineral, bauxite is an aluminum oxide mineral, and haematite is an iron oxide mineral. These minerals are all hydrophilic, and would not float in the froth flotation process.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[19],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Froth floatation process to concentrate the minerals is applicable to A.
