(WO2019/162362) CLAIMS 1. A method for detoxification of contaminated substances comprising the following steps:   i) providing a particulate magnetic composite material, wherein said particulate magnetic composite material comprises a surface and has a mean diameter particle size between 100 nm and 10 mm, and each particle of said particulate magnetic composite material comprises at least two magnetite particles, wherein said magnetite particles are embedded within a matrix of a non-magnetic material, and wherein there is a physical separation between said magnetite particles that is filled with said matrix of a non-magnetic material;   ii) contacting a contaminated substance with the particulate magnetic composite material of step (i);   wherein the contaminated substance comprises toxins;   wherein a partial or complete transference of said toxins from the contaminated substance to the particulate magnetic composite material by sorption of said toxins on the surface of said particulate magnetic composite material is produced and a partially or completely detoxified substance is obtained; and   iii) magnetically separating the particulate magnetic composite material from the resulting partially or completely detoxified substance of step (ii). 2. The method for detoxification as defined in claim 1 which further comprises the following steps:   iv) removing partially or completely the toxins from the surface of said particulate magnetic composite material resulting from step (iii) by washing said particulate magnetic composite material;   v) optionally, drying the particulate magnetic composite of step (iv); and vi) re-using the particulate magnetic composite of step (v) in step (i). 3. The method for detoxification as defined in claim 1 which further comprises the following steps: iv) removing partially or completely the toxins from the surface of said particulate magnetic composite material resulting from step (iii) by magnetic hyperthermia; and   v) re-using the particulate magnetic composite of step (iv) in step (i). 4. The method for detoxification as defined in any of claims 1 to 3, wherein the surface of the particulate magnetic material is chemically functionalized;   wherein the chemical functionalization comprises ligands; and   wherein said ligands are able to selectively bond toxins. 5. The method for detoxification as defined in claim 4, wherein the ligands are organic compounds comprising carboxylic groups. 6. The method for detoxification as defined in any of claims 1 to 5, wherein the contaminated substance is selected from contaminated water, food, feed and/or a mixture thereof; preferably contaminated food products or food raw materials; more preferably contaminated solid food products or food raw materials. 7. The method for detoxification as defined in any of claims 1 to 6, wherein the toxins are selected from mycotoxins, phycotoxins, cyanotoxins, subfamilies and/or derivatives of the same or a combination thereof; and optionally, wherein the mycotoxins, phycotoxins or cyanotoxins are selected from the group consisting of deoxynivalenol (DON), zearalenone (ZEA), fumonisin B1 (FB1 ), ochratoxin A (OTA), aflatoxin B1 (AFB1 ), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1 ), aflatoxin G2 (AFG2), microcystin-LR (MC-LR), microcystin-RR (MC-RR), nodularin (NOD), saxitoxin (STX), neosaxitosin (NEO), decarbamoylsaxitoxin (dc-STX), azaspiracid-1 (AZA1 ), azaspiracid-2 (AZA2), azaspiracid-3 (AZA3), dinophysistoxin-1 (DTX1 ), dinophysistoxin-2 (DTX2), okadaic acid (OA), pectenotoxin-2 (PTX2) and 20-methyl spirolide G (SPX20G), subfamilies and/or derivatives of the same or a combination thereof. 8. The method for detoxification as defined in any of claims 1 to 7, wherein the particulate magnetic composite material has a surface area per mass between 10 and 500 m2/g. 9. The method for detoxification as defined in any of claims 1 to 8, wherein the at least two magnetite particles are at least 10 superparamagnetic magnetite particles. 10. The method for detoxification as defined in any of claims 1 to 9, wherein the particulate magnetic composite material is superparamagnetic.   1 1. The method for detoxification as defined in any of claims 1 to 10, wherein the particulate magnetic composite material is superparamagnetic and it comprises superparamagnetic magnetite particles having a mean diameter particle size below 30 nm. 12. The method for detoxification as defined in any of claims 1 to 11 , wherein the matrix of a non-magnetic material embedding the magnetite particles is a carbon- based material or a metal oxide matrix. 13. The method as defined in any of claims 1 to 12 wherein the surface of said particulate magnetic composite material is porous. 14. Use of a particulate magnetic composite material, wherein said particulate magnetic composite material comprises a surface and has a mean diameter particle size between 100 nm and 10 mm, and each particle of said particulate magnetic composite material comprises at least two magnetite particles, wherein said magnetite particles are embedded within a matrix of a non-magnetic material, and wherein there is a physical separation between said magnetite particles that is filled with said matrix of a non-magnetic material, for detoxification of a contaminated substance; and   wherein the contaminated substance comprises toxins. 15. A composition comprising a contaminated substance and a particulate magnetic composite material, wherein said particulate magnetic composite material comprises a surface and has a mean diameter particle size between 100 nm and 10 mm, and each particle of said particulate magnetic composite material comprises at least two magnetite particles, wherein said magnetite particles are embedded within a matrix of a non-magnetic material, and wherein there is a physical separation between said magnetite particles that is filled with said matrix of a non-magnetic material; and wherein the contaminated substance comprises toxins.
