Today, limonite ores are mostly treated by leaching, where the ore is reacted with sulfuric acid and the dissolved nickel and cobalt are recovered as nickel-cobalt intermediate products. These intermediates can be refined to nickel metal or directly into the battery supply chain. ... They can almost always be upgraded at the mine site to a ...

The lemonite It is very common to find it in underground mines where groundwater with a high content of dissolved metals and low in oxygen mixes with oxygen-rich surface water and forms an iron-enriched precipitate that precipitates over the mine rock walls. this precipitate indicates what is known as acidic waters. Limonite Uses
Rocks and minerals that can be commercially mined for their iron content can be referred to as iron ores. The ores' colours vary and are caused by a high concentration of iron oxides. Iron can be found in many different forms, the most common of which are magnetite, hematite, goethite, limonite, and siderite. Types of iron ore in India
