Disclosed herein is a process for the recovery of a metal from an ore using a collector composition. The process includes contacting the ore with the collector composition. The collector composition can include sulfur-containing compounds comprising (i) mercaptans comprising branched C10 mercaptans compounds selected from the group consisting of 5-methyl-1-mercapto-nonane, 3-propyl-1-mercapto-heptane, 4-ethyl-1-mercapto-octane, 2-butyl-1-mercapto-hexane, 5-methyl-2-mercapto-nonane, 3-propyl-2-mercapto-heptane, 4-ethyl-2-mercapto-octane, 5-methyl-5-mercapto-nonane, and combinations thereof; and (ii) sulfides comprising branched C20 sulfides represented by the structure R1—S—R2, wherein R1 and R2 are each independently a functional group derived from an olefin, wherein the olefin comprises 5-methyl-1-nonene, 3-propyl-1-heptene, 4-ethyl-1-octene, 2-butyl-1-hexene, or combinations thereof.

The invention relates to a low-carbon olefine oligomerization catalyst and a preparation method thereof. A monomer N-vinyl pyrrolidone and trifluorostyrene are added to participate into polymerization in a polymerization process, and then sulfonated to generate the syrene cation exchange resin containing pyrrolidone in a skeleton. The catalyst disclosed by the invention has a high temperature resistant characteristic, is good in stability and yield of liquid products, and still can keep high catalytic activity after running for a long period of time. The resin catalyst disclosed by the invention is suitable for C3 and C4 olefine oligomerization reaction, so as to prepare C6-C16 olefins, and is especially suitable for a technology for producing nonene and laurylene by virtue of propylene oligomerization, a technology for producing a high-octane gasoline by C4 olefin oligomerization, a technology for producing isooctane by virtue of isobutene dimerization, and the like.

The invention discloses a method for producing nonyl phenol, which comprises the steps of: preheating phenol to a temperature between 115 DEG C and 125 DEG C, then fully mixing nonene at a room temperature with the preheated phenol, cooling to about 120 DEG C in a first-stage reactor, then putting in a second-stage reactor and dripping the nonene at the same time, cooling to the temperature of about 85 DEG C after the second-stage reaction, then reacting in a third-stage reactor and dripping the nonene at the same time, dephenolizing nonyl phenol reaction liquid obtained after three-stage reaction in a film evaporator, and distilling coarse nonyl phenol subjected to dephenolizing in a distilling still to obtain high-purity nonyl phenol. The method has the advantages of short reaction retention time, less by-products, small required power and low energy consumption, and the product produced has good quality. The whole production process is carried out continuously, has excellent stability, and improves production efficiency.
