A hydrometallurgical flowsheet (Figure 4) for the combined treatment of the Konkola Deeps sulphide deposit and Chingola refractory ore (CRO) has been proposed. The sulphide concentrate (40-45% Cu) is pressure leached under conditions that maximise recovery of copper and cobalt while rejecting iron as hematite. The autoclave discharge contains ...
This patented process produces a high strength nitric acid – typically around 55-60% HNO 3. Over 99% of the initial acid used in the leaching process is recycled. The 5% makeup acid is typically 30-80kg of acid per tonne of ore. Because the majority of the acid used is generated by the recycling stage, the DNi Process™ is not limited to ...

A hydrometallurgical method for precipitating iron in the form of hematite from leach solutions containing nickel, cobalt and iron, characterised by the steps of: i) pre-neutralising (12) the leach solution by the addition of a neutralising agent (14); ii) oxidising ferrous sulphate to ferric sulphate (16) by sparging air or oxygen into the solution resulting from step (i) at an elevated ...
The flow sheet is shown in Fig. 4. However, it is always useful to study if adequate enrichment may be obtained at a coarser size range. In this regard the liberation data shows that some liberation is achieved even at –210 micron. The process flowsheet developed with –210 micron size of BHQ does not give good enrichment of Fe values.
In order to understand the reason for low extraction efficiencies, two different theories were tested by performing different sets of experiments. The first theory was the arsenic's possible inhibiting effect on the dissolution kinetics of hematite and the second theory was the precipitation of secondary hematite …
A potentially environmentally-friendly and cost-effective flowsheet was developed that is adjustable to all REE magnets. • Concentrated nitric acid was mixed with up to < 1000 µm magnet powder to completely form a nitrate mixture in 1 h at 25 °C. Fe-nitrate completely decomposed by calcination at 200 °C for 1 h to insoluble forms without any REE-nitrate decomposition.

The Flowsheet for Hematite Benefication Process by Flotation. The above flowsheet has been developed to produce a high grade product economically with maximum recovery. Due to the flexibility of Units and especially the "Sub-A" Flotation Machine, gravity flow can be utilized throughout the mill, thus keeping pumping requirements to a minimum.
Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.
