SFMI has equipment to mill (crush) the ore and to extract (separate) the heavy material, which will include gold, silver, and maybe some stuff like copper, titanium, etc, and leave behind the silicates and lighter stuff that make up most of the rock. The "concentrate" they produce will be sent to a smelter to be refined. There was I think a news release or a blurb on their web site that described the equipment and process.
