The invention provides an ore whole-fraction pretreatment process and device. The device comprises a crushing system, an ore washing and screening system communicated with the crushing system, and an X-ray intelligent sorting system and a jigging operation system which are respectively communicated with the ore washing and screening system. The crushed ores are screened into + 12mm fraction and-12mm fraction through an ore washing and screening system, jigging operation is carried out on the-12mm fraction, and jigging tailings are subjected to crushing, screening, sand washing and fine sand recycling again to obtain finished sand; and carrying out X-ray intelligent sorting operation on the particles with the particle size of + 12mm to obtain crushed stones which can be used as aggregates. The waste throwing rate of X-ray intelligent sorting operation and jigging operation is high, the recovery rate of valuable elements can reach 96% or above, full-size-fraction efficient utilization of ore can be achieved, th
