Cramer's Mad Money Recap: Profit-Mining

"My point is that you can never let your politics interfere with your investing," Cramer said,

Another caller asked Cramer about consolidation in the industry. He said he could see Phelps Dodge and Alcan(AL Quote) as consolidators, and that Falconbridge(FAL Quote) and Southern Copper could be targets in the industry.

Cramer then moved on to the mineral-extraction picks. His first was Manitowoc(MTW Quote), which makes refrigeration equipment, and has a shipbuilding and maintenance business. But the main business to care about, Cramer said, is their "superior" mobile cranes.

In addition to benefiting from mineral extraction, Manitowoc should also benefit from the highway bill and rebuilding the Gulf Coast, Cramer said.

Cramer's second extraction pick wasn't a "best-of-breed" but was still underappreciated: Terex(TEX Quote) The company makes heavy trucks and construction equipment and Cramer likes them for their hydraulic excavators and surface trucks for mining. Cramer suggested investos buy the stock on any weakness.

A caller asked if there were any high-tech plays in the minerals sector. Cramer pointed her to Joy Global(JOYG Quote), which was a little more of a proprietary company.

Last, but certainly not least, was Cramer's selection of Caterpillar(CAT Quote), his "best of breed" for the mining equipment sector. "They make the best mining trucks in the world," Cramer said.

Furthermore, Caterpillar's construction equipment business should benefit from the highway bill. Also, it broke its union in the 1990s, so it's not saddled with pension and health care costs that are facing other industrials.

Caterpillar, Cramer said, "quite frankly is the best, and "you never need to apologize for buying the best."
