Nature of ore Ore may be present in quartz veins and (or) adjacent sulfidized wall rock. Gold is present as free grains in quartz, as blebs attached to wall rock ribbons, and in veinlets cutting sulfide grains. Individual veins are 1 to 10-m-wide discrete fissure fillings that have strike lengths of less than 100 m.

· KEMIO CONCENTRATOR SILICA FElSPAR Fig. 4. Process flowsheet of Kemi6 ore dressing plant. In the first flotation stage the mica is flotated by cationic collector in acidic circuit. In the second stage the feldspars are activated by HF and flotated. The tailing from this stage is the raw quartz which is further cleaned in the third stage.
The short answer to the question "What is the melting point of gold?" is 1,948 degrees Fahrenheit (1,064°C). The boiling point of gold occurs at 5,173 degrees Fahrenheit. The short answer assumes you are melting pure gold, but if other other alloy metals lare present (copper is the most commonly used base metal), then the temperature required to melt gold will vary.
