Do iron containing minerals, or feldspars, have a higher value?
Cold air intakes are a great bang for the buck. Its one of the first things people do to their cars to boost horsepower and torque. Once you have it in, it would make sense to get a minimum cat back exhaust for it too. It will really open up the air. Remember, it dosen't mean that it will boost it a 100 horses. It might give you form 8 to 20 at the most. But its the cheapest way.
iron ores do have a higher commercial than feldspars. There is more demand for iron ore than feldspar, especially an ore that's easy to process
Iron containing minerals is where iron is primarily recovered from, therefore, iron containing minerals and feldspar isn't that rare, making their value lower. Funny, I'm currently filling out a lab report on this. Small World.
By Volume and not just price.Iron minerals. Iron Ore. By value per ton bably Feldspars because they weather into Bauxite (Aluminum) and can be used for kitchen counters and ornamentation.
