In this paper, we make a detailed study on the hadronic production of the Ξbc baryon at a fixed-target experiment at the LHC (AFTER@LHC). In estimating the production cross sections, the (g+g), (g+c), and (g+b) production mechanisms are considered. For the initial heavy quarks, in addition to the extrinsic component, we also consider the intrinsic component. It is found that the (g+c) and (g+b) production mechanisms give sizable contributions to the Ξbc production, and the (g+b) mechanism dominates the production. The results show that there are about 3.40&#215;105 Ξbc events that can be produced per year at the AFTER@LHC if the integrated luminosity of the AFTER@LHC can be up to 2 fb−1 per year. Moreover, the intrinsic heavy quarks can have a significant impact on production, which inversely makes the intrinsic component be possibly tested at the AFTER@LHC.
