PROCESS FOR RECOVERING CHROME IRON ORE SMALL RESULTED FROM THE FERRO-CHROME MANUFACTURING PROCESS

摘要

the invention relates to a process for recovery of chromium ore maruntului of the manufacture ferocromului by briquetting,to be reintroduced into the technological manufacturing ferocromului in metallurgical industry. for this, the whole of chrome ore, fractia 0...10 mm, mixed with a binder in a ratio of 2. 7% (sodium silicate, molasses, and milk of lime or lye sulfitica) and water, the mixture is omogenizeaza for 10...15 min, then bricheteazala pressure of 100... 150 kg / cm cube shaped ovoidale 55 x 40 x 25 mm, after which stores the lighters is free for 30 days for drying in air.
