You really need to give a lot more information if you expect someone to be able to ID what you have. Poor quality pics alone aren't nearly enough.

See this post for some simple tests you can do yourself - http://www.mineral-forum.com/message-board/viewtopic.php?p=19487#19487

Try doing some of them, and posting the results and you may get a positive ID. You should also include the locality where you found it as well. Then maybe you would have a chance of getting a positive ID

Dear Makanudo,

As Kushmeja wrote, without more information, it is almost impossible for anyone to say with any certainty what minerals are in this rock. Your posting id. says that you are from Belgrade, and there are many mines with many ore minerals in that region, Serbia.

From the appearance, the MOST likely minerals that you have in these samples are sphalerite, zinc sulfide (dark brown), and pyrite, iron sulfide (metallic yellow). But there are many, many other ore minerals that they could be--these are just the most common and most likely ones, that have this appearance.

These being just small samples, it is really unlikely that you or anyone are going to determine for certain what they are. Your best chance would be to be able to show them in person to some experienced geologist or mineral collector, and see what they can say. As to what you might do on your own, if you are interested enough, read about these kinds of minerals that are likely to be present in the metal ores--starting with the two minerals I have mentioned--look up their appearance and properties, look at real examples of them (and learn what the other associated minerals are likely to be) in museums or elsewhere, and as you become better informed, you will gain more confidence in saying what they are likely to be.

That's really about all the advice we can probably hope to give you, on this Minerals forum.
