how malachite green ore is analysed for its constituents?

Answer 1

Add a piece of malachite to HCl 37%, and you will se bubbles, mmmh a carbonate mineral probably.

Add malachite to water and sonicate it for at least 5 minutes and misure pH, basic mhhh... hydroxycarbonate mineral....

Add sulfuric acid to malachite and put everything into a crucible and heat for 20 minutes until you have only a white powder into the crucible.
Add diluted sulfuric acid again, light blue color mmhh maybe copper, add ammonia, really deep blue color, yes it's copper.

Use the diluted solution of sulfuric acid into an Atomic absorption spectroscoper or an ICP to confirm that you have copper and to see if maybe there are other metals....no other metals...

Use X-ray diffraction to obtain the lattice structure: monoclinic.

Malachite is a carbonate mineral, copper(II) carbonate hydroxide Cu2CO3(OH)2. It crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses. Individual crystals are rare, but do occur as slender to acicular prisms. Pseudomorphs after more tabular or blocky azurite crystals also occur.
Malachite often results from weathering of copper ores and is often found together with azurite (Cu3(CO3)2(OH)2), goethite, and calcite. Except for the vibrant green colour, the properties of malachite are very similar to those of azurite and aggregates of the two minerals together are frequently found, although malachite is more common than azurite. Typically associated with copper deposits associated with limestones, the source of the carbonate.

have fun with your malachite

Answer 2

The quarantine tank is an rather good idea. You not in any respect pronounced how previous your tank change into, yet you probably did say you've been new to indoor fish. Did you cycle your tank proper? there's a good chace that the malachite eco-friendly is what killed them, notwithstanding it truly is likewise a threat that you had an ammonia spike from the malachite eco-friendly killing your constructive micro organism. Many drugs will do this. Malachite eco-friendly can truly be overdosed besides. Used proper, it could be very valuable in route of countless ailments recent in freshwater fish. The "fungus" you be conscious is likely a secondary an infection from an damage, and may be both bacterial or fungal. You did not element out your cleansing schedule, yet i ought to indicate that you siphon your tank once a week when you're literally not already doing it. it ought to also be a good idea to operate some rock salt to the tank besides. i'd not difficulty about taking away the fungus. it truly is in all likelihood lengthy gone with assistance from now. shop on with the suggestion above to get a quarantine tank on your new fish, and shop them in there for a minimum of three weeks in the previous including for your major tank.
