DEVELOPMENT OF THE FLOTATION TECHNOLOGY OF INCREASING OF IRON CONCENTRATE QUALITY AT THE CARMEN COPPER CORPORATION ENTERPRISE (PHILIPPINES)

摘要

There has been recently increased the interest of specialists and managers of ore dressing and processing enterprises to introduction of the technology of concentration of iron ore raw materials, directed on obtaining of more high quality marketable products. In the first place, it is connected with increasing of non-conditional concentrates' quality (less than 60% of the total iron), which extends the economical efficiency of ore-dressing and processing enterprises for metallurgical enterprises and decreases the costs on the metallurgical production stage. The Carmen Copper Corporation includes the Carmen concentrator, which processes the copper-porphy-ritic ores and produces the copper and magnetite concentrates. The copper concentrate is obtained by the flotation method. The magnetite concentrate is obtained by wet magnetic separation. Nowadays, the content of iron in the concentrate, obtained at the Carmen concentrator from the current extraction ores, does not exceed 50-51%, taking into account the high content of silica (to 18%).
