In a process for forming a bulk hydroprocessing catalyst by sulfiding a catalyst precursor made in a co-precipitation reaction, up to 60% of the metal precursor feeds do not react to form catalyst precursor and end up in the supernatant as metal residuals. In the present disclosure, the metals can be recovered in a chemical precipitation step, wherein the supernatant is mixed with at least one of an acid, a sulfide-containing compound, a base, and combinations thereof to precipitate at least 50% of metal ions in at least one of the metal residuals, wherein the precipitation is carried out at a pre-select pH. The precipitate is isolated and recovered, yielding an effluent stream. The precipitate and/or the effluent stream can be further treated to form at least a metal precursor feed which can be used in the co-precipitation reaction. The process generates an effluent to waste treatment containing less than 50 ppm metals.

1. A process for forming a bulk hydroprocessing catalyst, comprising: co-precipitating at reaction conditions at least one of a Group VIB metal precursor feed and at least a Promoter metal precursor feed selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, to form a mi
1. A process for forming a bulk hydroprocessing catalyst, comprising: co-precipitating at reaction conditions at least one of a Group VIB metal precursor feed and at least a Promoter metal precursor feed selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, to form a mixture comprising a catalyst precursor;isolating the catalyst precursor from the mixture, forming a supernatant containing at least a Promoter metal residual and at least a Group VIB metal residual in a total amount of at least 10 mole % of the metal precursor feeds;mixing the supernatant with at least one of an acid, a sulfide-containing compound, a base, and combinations thereof under mixing conditions at a temperature from ambient to 90° C. for a sufficient amount of time to precipitate at least 50 mole % of metal ions in at least one of the metal residuals, wherein the precipitation is carried out at a pre-select pH;isolating the precipitate to recover a first effluent containing less than 50 mole % of metal ions in at least one of the metal residuals in the supernatant;converting the metal ions in the precipitate or the first effluent into at least a metal precursor feed;recycling the at least a metal precursor feed from the converting step to the co-precipitating step; andsulfiding the catalyst precursor forming the bulk catalyst. 2. The process of claim 1, further comprising drying the catalyst precursor at a temperature of at least 150° C. before the sulfidation step. 3. The process of claim 2, wherein the catalyst precursor is dried at a temperature of at least 325° C. for the catalyst precursor to have the formula (X)b(Mo)c(W)dOz; wherein X is Ni or Co, the molar ratio of b:(c+d) is 0.5/1 to 3/1, the molar ratio of c:d is >0.01/1, and z=[2b+6(c+d)]/2. 4. The process of claim 2, wherein the catalyst precursor is dried at a temperature of at most 200° C. and wherein the catalyst precursor has the formula Av[(MP)(OH)x(L)ny]z(MVIBO4), wherein A is at least one of an alkali metal cation, an ammonium, an organic ammonium and a phosphonium cation,MP is selected from the group of Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, P is oxidation state with MP having an oxidation state of either +2 or +4 depending on the selection of MP,L is at least a ligating agent L having an charge n<=0;MVIB is at least a Group VIB metal having an oxidation state of +6,MP:MVIB has an atomic ratio of 100:1 to 1:100;v−2+P*z−x*z+n*y*z=0; and0
