EXTRACTION OF GOLD
Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver or sometimes with mercury ( amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles embedded in other rocks. Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. However, froth flotation processes may also be used to concentrate the gold. Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite. In this case, concentration of the sulfides results in concentration of gold values. Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation. If the gold cannot be concentrated for smelting, then it is leached by an aqueous solution:
- The cyanide process is the industry standard.
- Thiosulfate leaching has been proven to be effective on ores with high soluble copper values
A "refractory" gold ore is an ore that is naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both .Pre-treatment options for refractory ores include:
- Roasting
- Bio-oxidation
- Pressure oxidation
- Ultrafine grinding

Sir,
Sub: Mockery of Justice
This is in the reference with on going trial of dangerous terrorist 'Ajmal Amir Kasab'. Nearly one year back on 26/11/08 the whole world witnessed the dance of terror which left thousand dead and unknown figure of injured and a huge destruction in Mumbai. There is no need to elaborate the horror of this incident because the whole world watched whole drama on TV set. There was live coverage; thousands of video footage is there which is telling the whole story of this massacre. But since now ten months have passed and nothing has been done into this case.
Is there any doubt in the role of Ajmal Amir Kasab in this heinous act? Why he has not been punished yet. What are the authorities waiting for, are they waiting for some kind of trading. So, that Ajmal Amir Kasab’s fellow terrorists kidnap some prominent leaders relative and they can get the release of kasab. So many similar incidents has happened in past. When the terrorist got release of other terrorist in prison, in exchange of some high profile political leader’s abducted relative. Committing mistakes is not wrong but falling in same pit again and again is an act of foolishness and destruction. Before it gets too late this is right time when our country wake up and ensure that similar incidents don’t take place in future.
I request authorities to punish the guilty and ensure justice otherwise, ‘Ajmal Amir Kasab’ will be free one day and will continue to be threat to the whole of the humanity.
Thanking you,
Yours truly,

Writing Instructions
Instructions to be followed by people living in areas under risk of tsunami are:
• Find out if your home, school, workplace, or other frequently visited locations are in tsunami hazard areas.
• Know the height of your street above sea level and the distance of your street from the coast or other high-risk waters. Evacuation orders may be based on these numbers
• Plan evacuation routes from your home, school, workplace, or any other place
You could be where tsunamis present a risk. If possible, pick areas (30 meters) above sea level or go as far as 3 kilometers inland, away from the coastline. Follow posted tsunami evacuation routes; these will lead to safety. Local emergency management officials can advise you on the best route to safety and likely shelter locations.
• Find out what the school evacuation plan is if your children's school is in an identified inundation zone. Find out if the plan requires you to pick your children up from school or from another location. Telephone lines during a tsunami watch or warning may be overloaded and routes to and from schools may be jammed.
• Practice your evacuation routes. Familiarity may save your life. Be able to follow your escape route at night and during inclement weather. Practicing your plan makes the appropriate response more of a reaction, requiring less thinking during an actual emergency situation.
• Use a Weather Radio or stay tuned to a local radio or television station to keep informed of local watches and warnings.
• Talk to your insurance agent. Homeowners' policies may not cover flooding from a tsunami. Ask about the Flood Insurance Program.
• Discuss tsunamis with your family. Everyone should know what to do in a tsunami situation. Discussing tsunamis ahead of time will help reduce fear and save precious time in an emergency. Review flood safety and preparedness measures with your family.
