Abstract

The invention discloses a method for extracting nickel and molybdenum by a nickel-molybdenum ore all-wet method, relating to the smelting of nonferrous metals by a wet method, in particular to a all-wet method for extracting nickel and molybdenum from nickel-molybdenum ores of black rock series. The method is characterized in that during extraction process, pressure oxidation leaching is carried out to the nickel-molybdenum ores milled, thus obtaining a nickel leaching solution containing nickel and molybdenum and leaching slag containing molybdenum oxides; the leaching solution undergoes extraction for separating nickel and molybdenum, thus producing nickel salt and ammonium molybdate or molybdenum trioxide; alkali steeping in a normal pressure, purification and ammonium molybdate acid deposition are carried out to molybdenum contained in the leaching slag for recycling. The method of the invention has high nickel and molybdenum recycling rate, low production cost and environmentally friendly production process.

Description

technical field

[0001] The invention discloses a method for extracting molybdenum and nickel by a full-wet method of molybdenum-nickel ore, which relates to a non-ferrous metal wet smelting method, in particular a method for extracting molybdenum-nickel by a full-wet method of black rock series molybdenum-nickel ore. technical background

[0002] Molybdenum and nickel are non-ferrous metal elements with excellent properties, which are widely used in stainless steel, aviation, aerospace, chemical industry, electronics and other fields. With the continuous growth of the economy, the output of the iron and steel industry continues to increase, resulting in a significant increase in the consumption of molybdenum and nickel, and the contradiction between supply and demand is relatively prominent. The development and utilization of refractory mineral resources such as molybdenum-nickel ore in black rock series has attracted more and more attention.

[0003] In recent years, black...
