Abstract

The invention belongs to the technical field of biology and discloses a preparation process of a desulfuration, denitration and dust-removing preparation for smelting of ferronickel from laterite nickel ore. The preparation process comprises steps as follows: step 1) preparation of a mixed bacterial solution; 2) preparation of an adsorption carrier; 3) stirring and low-temperature drying. The preparation process is simple, feasible, simple to operate and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a preparation process of a desulfurization, denitrification and dust removal preparation for ferronickel smelting of laterite nickel ore. Background technique [0002] Laterite nickel ore resources are surface weathered crustal deposits formed by weathering-leaching-deposition of nickel sulfide ore rock mass. In the world, laterite nickel ore is distributed in tropical countries within 30 degrees north and south of the equator line, and concentrated in tropical-subtropical regions around the Pacific Ocean. Regions mainly include: Cuba and Brazil in the Americas; Indonesia and the Philippines in Southeast Asia; Australia, New Caledonia and Papua New Guinea in Oceania. 70% of my country's nickel ore resource reserves are concentrated in Gansu, followed by Xinjiang, Yunnan, Jilin, Sichuan, Shaanxi, Qinghai and Hubei, and the total reserves account for 27% of the country's total nickel r...
