Roasting and calcination: In metallurgy, the process of heating a concentrated ore in the presence of oxygen is known as roasting. This process is applied in the case of sulfide ores. For ores containing carbonate or hydrated oxides, heating is done in the absence of air to melt the ores, and this process is known as calcination.


Techniques for aseptic dressing and procedures

Dress the wound as per instructions. Note: Ensure that the materials and dressing pack are only used for one eye at a time to prevent cross-contamination. If, for some reason, another part of the face or the other eye also needs a dressing change, then open another pack and start on the other side with clean hands and gloves.


flotation | ore dressing | Britannica

flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity …
