Floor panel (1, 40, 51), wherein the panel is made as an oblong rectangular strip, comprising a first pair of opposite edges and a second pair of opposite edges, both pairs of opposite edges (2-3; 4-5) comprise coupling parts (6-7; 8-9), which allow to mutually couple a plurality of such panels to each other, - wherein said coupling parts at the first pair of opposite edges are configured such that two of such panels can be coupled to each other at these edges in a locking manner by means of a turning movement, wherein the coupling parts form a first locking system which effects a locking in a horizontal direction in the plane of the panels and perpendicularly to said edges, as well as form a second locking system, which effects a locking in a vertical direction perpendicularly to the plane of the panels, wherein the coupling parts are constructed as a tongue and a groove, which provide for the vertical locking and comprise locking parts, which, in the coupled condition, prevent the shifting apart of the tongue and groove, - wherein said coupling parts at the second pair of opposite edges are configured such that two of such panels can be coupled to each other by means of a downward movement of one panel in respect to the other, wherein the coupling parts herein also form a first locking system, which effects a locking in a horizontal direction in the plane of the panels and perpendicular to said edges, as well as a second locking system, which effects a locking in a vertical direction perpendicularly to the plane defined by the panels, wherein said first locking system is substantially formed of an upwardly directed lower hook-shaped portion situated at a first edge of said second pair of opposite edges, as well as of a downwardly directed upper hook-shaped portion which is situated at a second edge of said second pair of opposite edges, which hook-shaped portions can be engaged one behind the other by said downward movement, characterized in that said panel comprises a substrate of mineral material, which is realized on the basis of magnesium oxide and at least one binder, said binder being magnesium sulphate and/or magnesium chloride. - wherein said coupling parts at the first pair of opposite edges are configured such that two of such panels can be coupled to each other at these edges in a locking manner by means of a turning movement, wherein the coupling parts form a first locking system which effects a locking in a horizontal direction in the plane of the panels and perpendicularly to said edges, as well as form a second locking system, which effects a locking in a vertical direction perpendicularly to the plane of the panels, wherein the coupling parts are constructed as a tongue and a groove, which provide for the vertical locking and comprise locking parts, which, in the coupled condition, prevent the shifting apart of the tongue and groove, - wherein said coupling parts at the second pair of opposite edges are configured such that two of such panels can be coupled to each other by means of a downward movement of one panel in respect to the other, wherein the coupling parts herein also form a first locking system, which effects a locking in a horizontal direction in the plane of the panels and perpendicular to said edges, as well as a second locking system, which effects a locking in a vertical direction perpendicularly to the plane defined by the panels, wherein said first locking system is substantially formed of an upwardly directed lower hook-shaped portion situated at a first edge of said second pair of opposite edges, as well as of a downwardly directed upper hook-shaped portion which is situated at a second edge of said second pair of opposite edges, which hook-shaped portions can be engaged one behind the other by said downward movement, characterized in that said panel comprises a substrate of mineral material, which is realized on the basis of magnesium oxide and at least one binder, said binder being magnesium sulphate and/or magnesium chloride.
