Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Copper Mining and Extraction: Sulfide Ores

Processing Stages. Stage 1: Crushing and grinding The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a

Paraffin Embedding an overview ScienceDirect Topics

Embedding tissues in agar prior to paraffin embedding is very beneficial when working with small and friable samples (Lund et al., 1961).It minimizes the loss of tissue during vigorous processing procedures, allows placement of multiple small tissues within one block, and provides orientation for sectioning.

Cryosectioning: The Art of Sectioning Frozen Tissue

The property of the tissue to immediately stick to the cold steel makes this process even easier than paraffin embedding in many ways. The system provides distinct advantages over available methods for embedding tissue for frozen section, including speed, precision, reduced tissue wastage, ease of learning, and convenience.
