In order to protect the plants, you will need some sort of additional heat during frost and freeze events. Damage due to cold weather may be limited to the foliage, or may cause serious problems to the vascular system. If that system is disrupted too much, the inability to deliver nutrients to the rest of the plant's cells could be fatal.

It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material.

Chemical Beneficiation: Chemical processes can be used to remove specific impurities from the ore. For example, desulfurization may be performed to reduce the sulfur content of the ore. Heat Treatment: Some ores may undergo heat treatment to improve their magnetic properties, making them more amenable to magnetic separation.
