First thing comes into my mind is mining. Though I am no longer mining I started out with it and there would be alot of opportunities to make it more interesting.
I am a noob on RL minerals but i never have seen rocks which contain only one type of ore.
1. Use rocks which contain more then one type of ore (be it in a layered fashion where on the outside there is veldspar, then scordite, plag, pyrox, omber etc. you can do this all the way down to Arkonor cause the amount would be very small like 10 units per roid or even belt of 0.5 sec status)
2. Those roids would be much bigger in order to work
3. when you break through the first layer you would get a warning that you are changing to a different type of ore and if you would want to recalibrate your lasers to it. if you dont you get only like 5-10% of the ore out of it as a "side-product"
4. depending on how good your skills are the better the amounts are youre getting out of a layer
5. in 1.0-0.9 you get only 2 layers, in 0.8-0.7 you get all the current high sec ore but in less amounts, 0.6-0.5 you get all the ores from the empire but in lesser amounts (one more thing in #7) Nothing which is worth much, but which makes the whole belt more colorfull.
6. rats in belts are escalating up to like 2 cruisers and 1 BS in high sec. when you dont kill the rats after 10 minutes they get help from 1 cruiser, then after 20 minutes a 2nd cruiser, after 30 minutes the 2 cruisers and 3 frigs get one BS more. No more afk'ing mining.
7. make less static belts but more belts from missions. say a mission gets random ore. when the mission is completed, the belt in there can be scanned down easily (so should be blue'd wrecks). Those mission belts should work like the current high-low-null sec ore distribution. so a mission belt from a lvl 4 mission in 0.5 could contain even a small amount of arkonor. As i have said not much - say like 5-20 units. But this belt would be as colorful as it could get containing all possible ores in smaller amounts.
8. not re-calibrating resulting in mining ore in a new worse quality like instead of "dense veldspar" it would be "rusty veldspar" which would have -90% value of normal veldspar.

Main idea is to utilize the mining skills better, make it more colorful, more engaging (more rats, heavier rats, called to action for re-calibrating mining lasers). On the whole the value of a belt / belts in a system could stay around as they are. Just with more items.

Some people dont loot or even salvage. Therefore make blue wrecks be scannable very easy (like on the first scan run at 32 AU in a T1 frigate).
Also when a mission is turned it and the wrecks arent made blue - make them blue after 1 hr. (people might still want to salvage them after turning it in).
