Silicon powder (99.99 %, particle size 0.05mm) was ball-milled in an attritor ball-mill at 400 rpm for 30 h in hexane. It was found that slurry of ball-milled silicon in hexane was produced as a result of the milling. This slurry was sprayed into a silica tube at high temperature (800±1100℃) under an argon atmosphere.

Graphite And Copper. Use flood coolant, if possible. This is not always an option with manual surface grinders, but if you can, use it. Peripheral spray attachments also get the job done, with a big mess. You can learn a great deal from your supplier as well, some companies offer sound advice as well as products to make the process easier.

suitable to feed grinding mills" (Wills 1998). On a laboratory scale, in this project, the size of the ore required to feed the grinding mill was 4mm particle size. The crushed samples were sieved on a 4mm sieve. The samples passing the sieve (undersize) were then package in plastics to weigh 1kg. The samples that could not pass were
