Cataclysm has been out for two weeks, Lich King materials are starting to get some inflation in due to people not farming the materials so heavily, and I know most of you are just itching to sell your stockpile as soon as possible. I am going to tell you exactly what to do with all of that Saronite ore, how to properly diversify it to produce as much profit from it as possible.
Smelt the ores into bars, by doing so you're turning the ore into a 200% ROI, which is awesome in my opinion. You can sell the ore raw, but personally it's only going for 17-20/stack on my server, while the bars go for 45-55g per stack. Another way to go is to sell the bars to a vendor, I don't recommend this option as you're basically making back what you've spent, only do the price for saronite has crashed, which it should.
Make the ores into bars and then transmute it into titanium bars. While this isn't as big of a profit, use the bars to make items. The enchanting titanium rod is selling great due to the lack of titanium in the market. Make other titanium items if possible and sell them to levelers. If you cannot utilize the bars, sell them as is, they'll generally sell easily.
This is a great alternative to the other two. You'd be prospecting the ore and making rings out of the common green gems that you'd get. Use the eternal earth(s) that you've stockpiled ( hopefully you did! ) if you make rings, you'd be making 1-1.2k an hour, which is great.
You can use the uncommon gems to sell to levelers, cut them and post them at the Auction house. Lich King gems are still in market and still sell very well due to the over pricing of the Cataclysm gems.
In my opinion, this is the best possible way to use the ore, as you're making sure-fire profit while also making gold selling the uncommon gems to levelers.
Sell it raw
If none of the options above please you or you simply cannot do them due to lack of professions, you could always sell the ore raw. I managed to pick up my ore at 10-11g/stack and it's currently selling for 17-20, so I'm still making pretty decent gold. Selling the ore raw, you're targeting mostly Jewelcrafters, with Blacksmiths/Miners as well, it's a decent option, but I wouldn't recommend it.
Or... Wait it out
Simply wait! Cataclysm has been out for 2 weeks, and inflation is just barely setting in, a good stockpile will need to be held onto for 1-2 months before it's value goes up. To me, this is an excellent option if you're looking to make the most out of your stockpile.
I know it can be hard to wait, but patience is key is making gold, I can't tell you how many mistakes I've made by being inpatient. Back 3 months ago, I had 2 haunted memento's that I got for 500g each, I sold them at 1.5k each within 48 hours of buying them, I still regret not having patience to hold onto them and wait for the prices to inflate, If I had them now, I would of valued each one at 5-6k. Patience is the key, wait it out.
