Abstract: Provided is a flotation method for full-particle size recovery of a copper oxide ore. In this method, a composite grinding aid is used to reduce the surface hardness and compressive strength of copper oxide ore particles and mitigate the agglomeration of ore particles and the adhesion of ore particles to a mill liner and a grinding medium. A composite regulator is used to regulate the pulp environment and mineral surface properties. A composite collector is used to enable the selective enhancement of surface hydrophobicity for copper oxide minerals across different particle sizes. A cleaner scavenger stage is added to prevent a copper-containing middling from circulating and accumulating repeatedly at rougher and cleaner stages.

Abstract: An electronic device may be provided with a sensor module and an antenna having an antenna arm, ground structures, and a tuner. The tuner may be mounted to a printed circuit overlapping the sensor module. A spring may be mounted to the printed circuit and may couple the tuner to a conductive chassis of the sensor module. The sensor module may include optical sensors that gather sensor data through a display and may form ground paths from the tuner to the ground structures. Conductive interconnect structures such as springs may exert biasing forces in different directions to couple the ground paths to different layers of the ground structures. This may serve to couple the antenna to the ground structures as close as possible to the tuner, thereby maximizing antenna performance, despite the presence of the sensor module.

Abstract: Implementations of the present disclosure relate to methods, devices, and computer program products for event processing. In the method, first data associated with a first time window is obtained, the first data comprising a first object and a first group of events that are related to the first object. Second data associated with a second time window is obtained, the second data comprising a second object and a second group of events that are related to the second object, the second time window being different from the first time window. An event model describing an association relationship between an object and an event that is related to the object is determined based on the first and second data. With these implementations, multiple time windows are used in determining the event model, and thus the event model may have better performance in accuracy and immediacy aspects.
