At present days there are exploited two analogical ore bodies in Niná Slaná ore field. Deposit Manó - Gabriela and also deposit Kobeliarovo, that consist of metasomatic siderite with minor ankerite, both of them are of variable lens shape. Main mass of iron ore has undirect thickness of 250 m, whilst real thickness of layers is about 30 meters. Iron ore is exploited by using of underground minings methods. After crushing the exploited ore is ground and cleaned by magnetic separation. Upgraded fine concentrate is roasted at revolving furnaces with consequent moisture reduction. Final post treatment of product is pelletizing in muffling dums. Average iron content in pellets is 57% with subsidiary portion of 3,5% manganese.
