Abstract

The iron ore sample is processed in laboratory conditions with methods of both dry and wet magnetic separation. The particle size of the processed sample was 1 mm electric power of dry magnetic separation 0.2A-0.6A, and the rotation number of the separation drum was chosen to be 32 per/min. The most suitable procedures to get standardized concentrate are optimized through considering the following facts that the duration of wet magnetic separation is 20, 30, 40, 50 minutes, classification yield is 43.50 %, 55.70%, 72.70%, 85.20% for 0.074 mm crushed particles, and the electric power is 1A-5A of the wet magnetic drum. As a result of this process, the initial Fe concentration of the primary ore has increased from 43.59% to 65.60% and the recovery arose to 96.93%. Therefore, the combination methods of dry and wet iron ore separation are applicable for processing of iron concentrate with higher pureness that meets the requirements of metallurgical industries.

Чандмань-Уул ордын төмрийн хүдрийг хуурай соронзон болон нойтон соронзон аргаар баяжуулах технологийн судалгаа

Хураангуй: Төмрийн хүдрийг лабораторийн нөхцөлд хуурай болон нойтон соронзон баяжуулалтын хосолсон аргаар баяжуулсан. Нойтон соронзон баяжуулалтын нунтаглалтын хугацаа 20, 30, 40, 50 мин, 0.074 мм-ийн ангилал харгалзан 43.5%, 55.7%,72.7%, 85.2%-тай байхад соронзон орны 1-5А гүйдлийн хүч зэргээс хамааруулан стандарт баяжмал гарган авах технологийн зохистой горимуудыг тогтоосон. Анхдагч хүдэр дэх төмрийн агуулга 43.59% байсан бол туршилт судалгааны үр дүнд төмрийн агуулга 65.60% болж 96.93%-ийн металл авалттай төмрийн баяжмал гарган авсан. Иймд хуурай, нойтон соронзон баяжуулалт хосолсон схемээр төмрийн хүдрийг баяжуулах нь цаашид металлургийн үйлдвэрийн шаардлага хангасан өндөр цэвэршилттэй төмрийн баяжмал гарган авах боломжтой гэж үзэв.

Түлхүүр үг: Төмрийн хүдэр, хуурай соронзон баяжуулалт, нойтон соронзон баяжуулалт, төмрийн баяжмал
