Preparation Of Ferronickel From Nickel Laterite Via Coal

The sticking phenomenon between molten slag and refractory is one of the crucial problems when preparing ferronickel from laterite ore using rotary hearth furnace or rotary kiln processes. This study aims to ameliorate sticking problems by using silicon dioxide SiO sub 2 sub to adjust the melting degree of the briquette during reduction roasting. Thermodynamic analysis indicates that the .

Efficient Utilization Of Nickel Laterite To Produce Master

To lower the smelting temperature associated with the carbothermic reduction processing of laterite the optimization of slag and alloy systems was investigated to enable the reduction of laterite ore in the molten state at 1723 K. The master Fe-Ni-Mo alloy was successfully produced at a lower temperature 1723 K. The liquidus of the slag decreased with the addition of oxide flux Fe2O3 and .
