How do you get zinc from zinc blende?
Zinc can be obtained from zinc blende (also known as sphalerite) through a process called roasting. First, the zinc blende is heated in the presence of oxygen to convert it into zinc oxide. Then, the zinc oxide is further heated with coke (a form of carbon) to reduce it to metallic zinc, which can be collected for further use.
How do you drill through copper safely?
Use a titanium bit for best results. Clamp the piece of copper to a piece of wood if possible, so that the wood supports it from underneath, and give the drill bit a place to go once it goes through the copper. Wear safety gloves and glasses to keep from being injured by small shards of metal. When you drill through it, use a fast spinning speed with the drill, but don't apply a lot of pressure, just allow the drill bit to slowly work its way through the metal.
When Zinc plate was kept in a glass container having CuSO4 examine it found that blue colour of solution is getting lighter After few days when zinc plate was taken out no of holes were noticed?
This because when we place zinc in copper sulphate solution then due to lower reduction potential and higher oxidation potential it consists the ability to loose electrons to copper as copper have more reduction potential (0.34) therefore it gains electrons from zinc. due to transfer of electrons the colour faints and after some days we will see that whole of the zinc gots oxidised and becomes zn2+.

Steel framed doors?
Expensive door jams have screw holes for tapcoms to install into concrete foundation or wood framed jams. Cheap door, you have to morter the jam in place. I drill a 1/2in hole through the rise plate(frame stop ) then drill hole size of screw through the outer plate that is against the foundation or jam. This way you do not see the screws that are holding the frame.
